It can causes electricity accidents and interference in Power system Therefore, the application of filter facilities is essential to prevent the effect of Harmonics in Power system and use electricity more efficiently. 〉 What is harmonic Cyclic distortion wave is expressed as the sum of sine wave [50Hz], the integral number frequency and major sine wave, integral number [50Hz] frequency. This integral number frequency is called harmonic wave and according to the amplitude change and phase, wave form is changed resulting in synthetic distortion. Combined distortion wave is manifested in distorted sine wave form. This form can be analyzed into one fundamental wave [50Hz] which has random cycle and major sine wave which has integral number frequency or subharmonic frequency. If the frequency of it is higher than the fundamental frequency, it is called harmonics and if the frequency of it is lower, it is called fractional harmonic wave or subharmonic. For example, an distorted wave form comprising sine wave type [50Hz] and 5th [250Hz] and 7th [350Hz] wave form is analyzed as following : = + + ex ) Harmonics = Fundamental frequency + 5th Harmonics + 7th Harmonics 〉 Harmonic Generator 〉 Process of Harmonic •Thyristior controller Filter Engineering •Speed controller • Collecting data[system condition, harmonic •Low speed starter spectrum, THD limit] •Power factor compensator •Drawing system impedance map •Rectifier • Calculating harmonic impedance and determining •Arc furnace filtering order •Transformer, Reactor •Harmonic flow calculation •N on-linear loads such as rotating devices •Simulation changing the wave form of the current which • Checking abnormal resonance in the system and generates harmonics. the possibility of harmonic extension •Designing Switcher PNL, Structure •Testing the operation after installation •Test reportSamwha 28

Special Capacitor, 4-8 Water Cooling Capacitor 〉 Application This product is specially designed to accommodate high capacity to be easily used for matching circuit of high frequency induction furnace device. For dielectric, polypropylene film and capacitor paper were used together and aluminium foil electrode of non induction method was used. For insulating oil, non PCB dielectric was impregnation resulting in stable and excellent feature. For cooling method, it was designed that cooling water can absorb the heat generated from the inner dielectric loss. To make matching circuit easily when inductive load is changed, capacity was divided into proper capacity and lead bushing was treated. The material of case is non magnetic aluminum to minimize induction loss due to high frequency electric filed. The loss of capacitor itself is about 0.1%. Maximum Water temperature rise should not exceed 4deg [5l/min] on the standard of maxim capacitance. Permissible load power is 1.05 times of rated voltage [within1 hour per day] and maximum permissible current is 1.35 times of rated current. High frequency water cooling capacitor does not contain discharging resistor since it is connected to high capacity coil circuit in paralleled. When capacitor is input into circuit again, the permissible limit of residual voltage should be within 10% of rated voltage and nuts with DC voltage. Tightening strength on nuts at terminal is 200kg·㎝ or less. 〉 Technical data Stream Flow Installation place Only for Indoor (ℓ/min) Temperature of Cooling water exit temperature less than 45℃ Cooling Water Ambient Temperature More than 0℃ Tolerance Within ± 10% of rated capacity Withstand Voltage 2.15 times of rated voltage, 10 seconds Flux of Cooling Water More than 5ℓ per minute Pressure of K : Series Logarithm of Coolling Coil Less than 10kg/㎠ Notes) Pipe Dia(12Ø 1.0t) Cooling Water Pressure Safety Device Thermostat contact capacity [250VAC, 7.5A] (㎏/㎠) Case Aluminium non painted product 〉 Caution Since the outer case of capacitor is unilateral electrode, please be sure to use the insulated rack in installation.

Special Capacitor, 4-9 Surge Absorbing Capacitor 〉 Operation principle To explain the effect of surge absorbing capacitor, the rotator is expressed as intensive equivalent resistance R as in the figure A. In parallel with this, on the circuit to which the protecting Capcitor is connected, VO = EOH[t] travelling wave invaded from line of surge impedance Z. Then terminal voltage of R and C is Vc, the current Ip at P point Is dVc11Ip = C ── + ─ Vc = ─ [2Vo - Vo] dtRZdTo rearrange the expression ── = P, Vo = EoH[t] dt R+Z 2Eo PVc = ( ── (Vc = ── H[t]CRZ CZ ( R+Z──CRZ ( = α 2Eo 1 2Eo Vc = ── × ── H[t] = ── [1-e-αt] H[t] CZ P+α αCZ When Z and R is constant and C is changed, the terminal voltage of the rotator Vc is as in the figure B. From this, it can be seen that the wave height value is reduced according to the value of C or R. When R = ∞ and C = 0.3㎌, the terminal voltage of the rotator is reduced to 1/2 of invasion wave, which shows the effects of surge absorbing capcitor. Vo Ip Figure A Voltage Time(㎲) Figure BSamwha 42

Please contact factory for exact deimensions of a particular capacitor 〉 Operation Principle In 3 phase circuit, for 1 line grounding current is calculated from the following formula. lg = 3jωCEa = j√ 3E×2πfC Ig : Grounding Current [A] E : Line Voltage [V] Ea : Phase Voltage [V] C : Equivalent Ground Capacitance [C = C1+C2] IC1 [Ground fault current Ig in figure A - charged current after zero phase current transformer [ZCT]] passes the zero phase current transformer. Therefore, ground fault current Ig1 passing ZCT can be calculated from the following formula. Ig1 = √3E×2π×f×C1 When the distance between transformer and ZCT is small, ground capacity in line is small and penetration ground fault current Ig1 is not enough to move circuit breaker. Therefore, use capacitor for earthing to improve ground capacity in line. For example, when E = 3300V, C1 = 0.5㎌, and f = 50Hz in figure B, ZCT penetration ground fault current is as following : Ig1 = √ 3×3300×2π×60×0.5×10-6 = 1.08A Since detecting current of grounding breaker is selected to be 0.1 ~ 0.8A, it is good to select the value of C1 to be more than this value [C1 is equivalent to 1 phase and in case of C1 = 0.5㎌, capacitor for grounding of 0.5㎌×3 is to be selected] Grounding Transformer Grounding Capacitor Grounding Transformer Grounding AccidentSamwha 44

6. Appendix Power Factor Before Imporovement = cosθ1, 6-1 Capacitor Calculation < Guid for Capacitor Selection > 1. Before choosing capacitors Consider the quality and after service of capacitors Access power capacitors as the aspect of power compensation to use energy more efficiently 2. Knowing Capacity you may need To know the necessary capacity, follow the under steps Step 1. What is the value of full load power being operated in kW? Step 2. What is the value of power factor [cosΘ1] at present? In case of New factory, power factor of each load might be changed, so it needs to be investigated. Step 3. Set the value of target power factor [cosΘ2] Step 4. Using aboved values, calculate the necessary capacity using formula or capacity table offered. For example >> The value of load power is 1000[kW] with power factor 0.75. But your target power factor is 0.95. ① The formula to get the value of capacity 1− cos 2 θ1 1 1− cos 2 θ2 Qc = P× − 2 cosθ1 1 cosθ22 = P× (tanθ11 − tanθ22 ) = P×{(tan ⋅ cos −1 −1 Qc : Capacity [kvar] (cosθ11 ) − tan⋅ cos (cosθ22 )) { P : Load [kW] = 1000 × (tan ⋅ cos −1 0.75 − tan⋅ cos −1 0.95) cosθ1 : Power factor at present = 553[kvvaarr]] cosθ2 : Target power factor setting ② Using Capacity Table offered Find the value of crossing point on the table between power factor at present and the target power factor. In this case, the value of crossing point between power factor 0.75 and target power factor 0.95 is 55% And multiply load value and the corrosing point value together. Qc = 1000×0.55 = 550[kvar] Notes > 1. With the value of Capacity more than 300kvar on high voltage and more than 50kvar on low voltage, capacitors can not prevent harmonics and inrush current themselves. Therefore, series reactor needs to be installed together with capacitor. Also it is recommended installing discharging coil to make sure perfect discharging performance. 2. The units to express capacity are ‘kvar’ or ‘㎌’. Following formula is for conversion of those two units ; Qc = 2 × π × f × C × V2 × 10-9[kvar] Qc × 10 C : Capacity [㎌] C = [㎌]2 × π × f × V2 Qc : Capacity [kvar] f : Frequency [Hz] V : Rated voltage [V] π : Integer [3.141592654] 57 Samwha 6.

The cubicle shall not sealed tightly and ambient temperature of the Capacitor shall be less than 40℃ in summer. 4] Use the brackets attached to the body for transpotation and be sure not to grasp the bushing. 5] Use twisted wire for connecting to capacitor.The square of wire shall be more than 1.35 times of rated current of capacitor. 6] Earth of capacitor shall be grounded with No.1 type grounding construction [less than 10Ω] 7] Capacitor has been produced with built in discharge resistance so that when it is opened from the circuit, the residual voltage can be reduced to less than 75V within 3 min. If the switch is turn on again when the residual voltage is not discharged enough, DC voltage becomes double and can be the cause of damage to capacitor. When it turns on/off within short time [within 5 seconds], discharging coil is desirable. 8] If the capacitor is connected in series to induction motor as in the picture below, select the capacity to be the same with non load excitng current when capacitor current ≤ IM.[to prevent voltage rise against magnetic excitation.] < General maintenance check points > 1] M aximum permissible voltage is within 110% of rated voltage. Confirm of the equilibrium on each phase. Please be careful of circuit voltage rise in slight load at night. If over voltage is applied to capacitor continuously, kvar quantity is increased relative to 2 square voltage rise which results in the increase of loss and rise of temperature leading to shortening of life span. 2] Confirm that current of capacitor is within 130% of rated current. 3] W hen more than 120% of rated current flows on capacitor, please check the current wave form with oscilloscope to know which harmonics current is the cause and install series reactor to control harmonics. 4] T he temperature of capacitor case is designed to be less than 65℃ in mid summer [ambient temperature 45℃] 5] Always check the current and voltage of capacitor circuit [3 phase equilibrium], clean bushings : more than once per 6 months [according to the state of contamination], measure capacity and insulation resistance : once per year. But, for measurement of insulation resistance, confirm that DC mega measurement shall be more than 1000MΩ[per unit] between terminal and case 6] C heck the connection part of the electronic switch used in capacitor circuit once per year to a minimum. If the connection is not perfect, single phase operation or harmonics agitation voltage may be applied to the capacitor and it wil reduce the normal life span 7] Open the capacitor from the circuit when leading power facotr in slight load at night. 59 Samwha 6. Appendix, 6-3 Maintenance < Maintenance points to Prevent Accidents > To contact capacitor terminal for examination, open the switch on the side of power supply and leave it for 5 minutes as it is until the residual voltage goes below 50V. Then, use earth stick to discharge the residual voltage entirely and check the charging part. 1] The maximum permissible voltage of capacitor is less than 110% of rated voltage [within 12 hours per day]. Confirm that each phase is in equilibrium. Especially at night or afternoon, be careful to check the rise of circuit voltage. When over voltage is applied to capacitor, kvar is increased relatively 2 square of the voltage rise resulting in excessive increase of temperature of capacitor, leading to shorten life span. Therefore, it is desirable to separate the capacitor from the circuit in slight load. 2] The maximum temperature of capacitor case is designed to be 40℃ to 60℃. If this limit is exceeded, forced wind cooling shall be employed to reduce the ambient temperature. 3] Capacitor expands or contracts according to the change of temperature and the bend of case surface absorbs this expansion or contraction. In operation, case expands about 15mm on the side by the inner insulation oil. If the expansion is below 15mm, it is normal. If the case expands about 15mm and abnormal function is suspicious, should check the current. The current of each phase is within permissible limit of rated current and in 3 phase equilibrium, then capacitor is normal. 4] Always check the current of capacitor. 5] C heck the contact part of breaker or switch used in capacitor circuit once per year. If the contact is bad, capacitor would be operated in single phase or abnormal noise may be heard due to bad connection. High frequency agitation voltage is applied to capacitor leading to notable shortening of life span. < Routine maintenance check points of capacitor > Check Points Problems Solutions If oil leaks, change the capacitor. Oil leakage at bushing [Being left for a long time, it may be led to destruction of insulation] Leakage of Oil and If oil leaks, change the capacitor.
