UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...
