Heavy Current Arc Ignition Test Apparatus , Electrical Material
Test Equipment
Product information:
This device conforms to standard requirement of IEC 60950-1,BS EN
60950-1,BS 7002, UL746A,IEC60947.1, IEC730.1. It is suitable for Arcing resistance
test of electric and electronic products, household appliances and
its materials. The working principle is to simulate the electric
leakage on the insulator which may cause among different polar of
live parts or between live parts and grounded (earthed) metal parts
It is used to measure and assess the arc resistance performance of
insulator under the prescribed voltage.
Heavy current ignition tester adopts dual electrodes. With specific
current (33A) and power factor (COSφ0.5), according to a certain
arc strike speed (254mm/s) and repetition frequency (40 times/min),
repeatedly arc strike to 200 times on the surface of specimen. The
large current arc ignition performance (HAI) can be assessed
according to whether the sample can be ignited. The smaller of the
grade number, the more difficult for burning material.
