3 HIGH VOLTGE POWER PITOR EQUIPMENT (Oil illed & Self-cooled) TYPE LV-6 HIGH VOLTGE POWER PITORS & RETORS HIGH VOLTGE POWER PITORS LV-6 high voltage power factor correction capacitors employ the plastic film only having superior dielectric strength and utilize the electrodes of unique construction, achieving low loss (as low as approx. /3 of our conventional capacitors) and significantly high current handling capability. ETURES q Extremely Low Loss to Save Energy The use of all plastic film dielectrics and proprietary electrode construction has reduced the loss of film itself to approximately /3 of our conventional design, offering significant saving in capacitor operation cost. w Higher Safety actor for Temperature against Harmonics Temperature rise has been reduced considerably (to approximately / of our conventional design) due to lower loss, providing a higher safety factor for temperature against overload caused by harmonic currents. In addition, the capacitors can be operated at up to (temperature class ) due to lower temperature rise during operation. e Enhanced urrent Handling apability The proprietary extended foil construction has enhanced greatly the capability to handle inrush current appearing when the capacitors are switched on or off. r Superior Reliability The use of polypropylene film dielectrics with excellent electrical performances has enhanced dielectric strength and reliability. t ault etector (M-) for kvar or more The fault detector is free of leaks to provide high reliability, with its simple construction to facilitate maintenance and easy mounting. ENERGY SVING If LV-4 kvar x 0 units are replaced with type LV-6, annual energy saving will amount to (-) W x 0 units x 4 hr x 365 days = 3,4kWhr.

Required capacitor output = 0kW x 0.55 = kvar w or loads rated at kv, calculate in a manner to similar to q by converting kw=kvxcosf.

4 HIGH VOLTGE POWER PITOR EQUIPMENT (Oil illed & Self-cooled) TYPE LR-3 SERIES RETORS Multiple capacitors connected to a circuit for power factor correction may cause the waveform of the circuit voltage especially the 5th harmonic to be distorted more. This is because the capacitors connected make the impedance of the circuit capacitive. Harmonics contained in the voltage waveform may increase noise in a transformer, or may cause an excessive current to flow through the capacitor circuit resulting in a failure of the capacitors. To solve these problems, reactors should be added in series with the capacitors to make the impedance of the circuit inductive for harmonics for the improvement of the distorted waveform. Series reactors are used for this purpose. Series reactor will improve not only the waveform but also will help reduce the inrush current that will flow through capacitors when the capacitors are switched on or prevent switches from restriking when the capacitors are switched off. PPLITION NOTES Noise Series reactors are constructed to provide air gap in the core. Special consideration is given to the design and manufacture of the series reactors to minimize buzzing to be generated by the air gap. When series reactor are installed in a small sealed room, buzzing may be echoed or resonate with that of the existing transformer resulting in amplified buzzing. To prevent this problem, it is recommended to secure reactors on the floor tightly by foundation bolts. If buzzing is still audible, add a rubber pad. Higher content of harmonics may cause a higher noise, but does not affect the performance or life of the reactors adversely as long as the current flowing in the reactor does not exceed the permissible limit. Matching with capacitor output Series reactors are intended to be connected in series with other device, and work effectively when combined with a capacitor whose output matches with that of the reactor. or example, a 6.38kvar reactor will have 6% reactance to improve the waveform of the 5th harmonic only when connected to a 06kavr capacitor. When connected to a 53.kvar capacitor, the 6.38kvar reactor will have an output of 53.kvar 6.38kvar x 06kvar =.6kvar Therefore, it will have 3% reactance for the 53.kvar capacitor and will not work effectively for the 5th harmonic. It may amplify harmonics. ddition of series reactor to some of capacitors If some of capacitors installed in the same system do not have series reactors, harmonics may be amplified depending on percentage of capacitors without reactors. It is recommended that the capacitors which account for at least /3 of the total output be provided with a reactor. IRUIT PROTETION When harmonic current exceeding the limit flows in the reactor, the reactor may burn out. onnect the Thermal Sensor attached to the reactor to a circuit breaker to protect the reactor.

13 HIGH VOLTGE POWER PITOR EQUIPMENT (Oil illed & Self-cooled) PROTETION O HIGH VOLTGE PITORS & RETORS High voltage power capacitors can be said to be a static apparatus with extremely high reliability. However, overheat, burning out, short circuit or case rupture may occur, should a capacitor fail due to service conditions including overvoltage and excessive harmonics. Therefore, it is required that capacitors be protected against failure. Protection should be coordinated with failure characteristics of capacitor equipment and the following protections are recommended. Rated Equipment Output 0kvar - kvar kvar - 0kvar HIGH VOLTGE PITORS ault etectors (M-) Recommended Protection urrent limiting fuses & thermal sensors ault etector (M-), current limiting fuses & thermal sensor (Notes). or recommended rated current of fuses, refer to the recommendation of the fuse manufacturers.. Install fuses at the power supply side of series reactors. 3. apacitors rated at kvar or more can be supplied with double star connection. Large kvar capacitors will develop a zone where the case rupture can not be protected by current limiting fuses if the breakdown will last for a long time. onveniently, it is known that the larger the capacitor kvar or for capacitors with star connection, the more the case bulges. M- fault detector will sense the bulge in case to protect the case rupture. Excessive bulge in the case caused by failure in the capacitor will activate the micro switch which will then generate the signal to trip a circuit breaker. of ontact ontact apacity Voltage(V) urrent() ielectric Strength a+b () () 0() () V, minute (Notes).

26 HIGH VOLTGE POWER PITOR EQUIPMENT (RY) PROTETION O GS ILLE HIGH VOLTGE PITORS & RETORS GS ILLE PITORS Gas filled capacitors are designed to give high performance and reliability including tight gas seal capability and self-healing properties by the implementation of totally sealed construction and metallized film dielectrics. However, the following protection schemes are implemented just in case any failure occurs. () If gas leakage occurs, The lower pressure limit switch will be activated when the capacitor s internal pressure will be reduced to the ambient pressure. Use the contact circuit of the pressure switch to give an alarm or disconnect the capacitor. The capacitor will not need to be disconnected immediately after the alarm sounds. However, it is recommended to disconnect the capacitor within 4 hours. () If the capacitor be internally broken down, When the internal windings will be broken down, a fault current will flow and the decomposed gas will gradually increase the internal pressure. The upper pressure limit switch will be activated when the internal pressure reaches the specified level. Use the contact circuit of the pressure switch to open a capacitor switching device or a circuit breaker in the upper stream. Install current limiting fuses to protect capacitors from momentary short failure in the capacitor. Selection of fuses should be made in the same manner as the oil filled capacitors. SERIES RETORS Protection Method JIS 4 specifies that series reactors for power capacitors shall be operated at a current which contains the 5th harmonic current of not more than 55% of the fundamental current with the root of the sum of the squares limited to not more than % of the rated current. If the 5th harmonic voltage distortion is excessively high, some current exceeding the limit will flow through the reactor possibly causing excessive temperature rise to burn out the reactor. The reactors are equipped with a Thermal Sensor to detect excessive temperature rise. onnect the sensor to a circuit breaker (or a switching device) located in the upper stream to disconnect the reactor from the power source.

38 3 LOW VOLTGE POWER PITOR EQUIPMENT REE STNING ENLOSE V-P II (with L=6%, I5=55%) The Shizuki V-P II low voltage power factor correction equipment has achieved the utmost effect to save electric power. The equipment consists of the control unit to detect and control power factor, the thyristor switches to switch on and off the capacitors with solid-state switches, and the capacitors combined with the reactors. The equipment has automatically maintained the desired power factor level, adjusting to the system load requirements. ETURES q The capacitor switches use contactless thyristors with no mechanical moving parts, providing a semi-permanent life. In addition, the employment of soft-start circuit smoothes the building-up of current waveform, eliminating inrush current. w The series reactors (6%) combined with the capacitor suppress the amplification of harmonics present on the line and reduce inrush current flowing from the line. SPEIITIONS e The automatic capacitor control unit Q-UTO with a built-in microcomputer maintains the system power factor at nearly %. r Special care is given to the safety design, employing the capacitors with a built-in protective device and incorporating alarm contacts in the automatic capacitor control unit to monitor low power factor.

39 4 SURGE SORING PITORS & GROUNING PITORS TYPE NV- Surge bsorbing apacitors bnormal voltage appearing on the line is caused by the internal factors including switching of the circuit, opencircuit, short-circuit and grounding or by the external factor of lightning. The abnormal voltage is propagated on the line to apply excessive voltage to transformers, circuit breakers, potential transformers and current transformers installed at a power plant, and is further transmitted to the generators or rotating machines through the secondary of the transformer, damaging them. Rotating machines and transformers are generally installed in a narrow facility. Therefore, it is hard to enhance the dielectric strength of the apparatus. Surge absorbing capacitors help protect the apparatus from the abnormal voltage more effectively than any other methods. escribed below are the benefits and characteristics of our surge absorbing capacitors. ig. shows the circuit where a surge absorbing capacitor is connected on parallel with a lumped resistance R which represents loads such as generator or transformers. ssuming transmitted wave E0=e αt e βt, the terminal voltage across the load E will be To find out how the capacitor helps reduce a surge, let us assume in ig. the surge impedance at the side of the transmission line Z=Ω and the surge impedance of the apparatus to be protected R=,000Ω. The results of calculation are shown in ig. which tells us that the sharper the transmitted waveform is or the larger the capacitance is, the more effectively the capacitor works.

41 5 HIGH REQUENY PITORS PLSTI ILM PITORS (ETHY-ON) Our polyethylene film capacitors were originally developed for the integrating circuit of analog computers. The application was later expanded, because of its low dissipation factor, to include power factor improvement in the high frequency SR and Motor Generator (MG) type electric furnace heating equipment, and in vacuum tube high frequency oscillators for oscillation, bypassing, or blocking. The capacitors, called Ethy-con, have enjoyed good customer acceptance. With the introduction of electrical grade polypropylene film offering a unique characteristic, our efforts made it possible to successfully develop and market polypropylene capacitors for application in the MG type high frequency electric furnace to improve power factor over the range from KHz to 0 KHz. oth polyethylene and polypropylene film capacitors have been found to be acceptable among customers for high frequency applications.
