Model: G0003-5

The Glow Wire Thermocouple allows for a test to be carried out assessing the effects of heat generated by electrical faults and overloads within electrical equipment in solid insulated materials and non-metallic enclosures containing or supporting current carrying parts with regard to ignitability and propagation of flame.

An electrically heated small loop of resistance wire “Glow-wire” is applied to those insulation surfaces likely to be subjected to heat generated by fault conditions or overloads. The temperature and duration of application of the glow-wire is dependant upon the operational and service conditions of the equipment under test. The glow-wire thermocouple is an integral part of this test.

The glow wire must be introduced at right angles to the test specimen with a force of 0.8 to 1.2N and the glow-wire and test specimen must be moved towards each other over a distance of up to 7mm.

Calibration of thermocouple is to be carried out at 960˚C.

Preferred test temperatures are:
• 650˚C
• 750˚C
