Power Supply Circuit Protection Protection of relay (Contact coil) ① Connect the SVC at a position nearer to the equipment than the overcurrent protection device“Ⅰ”(fuse, MCCB) as is shown in the diagram. When the SVC is shorted, the overcurrent protection device “Ⅰ”operates (trips or blow off the fuse).

DISC Ceramic Capacitors 131 Capacitance Test current waveform Typical values measured at a test frequency of 1kHz Characteristics tests for Varistors are carried out by using 8/20㎲ test impulses Data such as the maximum clamping voltage(Vc)and the transient peak current(Itm) are obtained by using this impulse current Rated peak transient current : itm Maximum peak current through the varistor with line voltage applied. The maximum peak current with in the varistor voltage change ratio of ±10% with the standard 8/20㎲ impulse current applied two times at 5 minute interval. However, for the Vc characteristics of the Axial Package type a 10mA DC squarewave current is used to cary out the test.

Pulse lifetime rating Rated average power dissipation : Ptam This is expressed as the maximum allowable number of impulse currents applied. Maximum average power that can be applied within the specified ambient temperature. 8/20㎲ impulse current(or 2ms square wave) is applied at prescribed interval. This curve also provides for derating current as required with repetitive pulsing. www.samwha.com 132 SAMWHA CAPACITOR Co., Ltd.
