When an A.C. capacitor bank is used to the circuit to improve the power factor and regulate the voltage, the distortion of the voltage and current waveform can be alleviated. The switching of A.C. capacitor bank leads to the transition of attenuated oscillation apart from general inductive circuit, and during operation, large immersion current is generated. To control these phenomena, you must insert a series reactor into the capacitor bank. The details are stated as follows.
1) Surrounding temperature : -20℃~+40℃ 2) Average surrounding temperature during 24hrs : 35℃ or under 3) Above sea-level : 1000m or under
1) Capacitive allowance : -5~+10% 2) Insulation resistance : 500MΩ and over 3) Max. using voltage : less than 110% of the rated voltage 4) Max. using current : contain the 35% of the fifth harmonic to the basic wave current and the compound current is 120% or under
Repair and checking
In operating the series reactor, if you check the followings, you can safely operate it electrically and mechanically. 1) Since the reactor has a little vibration during operating, the connection part may be  loose fitting. Therefore you must operate after confirm it. 2) You must certify the contamination of the insulation oil(O.T) 3) If you operate again after stopping flow at long time, you must check the above item 1), 2) 4) If the current is over flowed 120% of the rated value, though the voltage is rated value by ascertaining the condenser current during the current is flowed, the reason is considered that high frequency harmonic is superposed and you must flow the current after certifying the problem. 5) You should prevent the reactor and condenser from breaking by regulating condenser groups in order to incline the power factor toward the lead phase. 6) When the power source is broken, though the inside-loading reactor have the discharge coil, however you must do work after checking the reactor terminal surely.
