Glow Wire Tester for IEC60695-2
Glow wire tester simulates the flame inside the device is easy to spread insulation or other solid parts of combustible materials may be due to sky glow wire ignition or burning components. Under certain conditions, such as the fault current flows through the wire, the overload element and a lower bad contact, the temperature reaches a certain component parts near to the ignition test.
