High Voltage Continuity of Covering Tester
Instrument Description
High voltage
- A voltage generator must provide the electrode with a continuous filtered voltage without transients. The test voltages using an open circuit must be adjustable from 350 to 3000Vdc+-5%.The permanent short circuit current must be 25±5μA at any voltage. A 50 Mohm resistance applied to the high voltage electrode should not cause a voltage drop more than 75% irrespective of the voltage used; the specimen length shall be 30 meters. An appropriate circuit must evaluate whether the wire carries a current which is greater than that specified in the tables; a counter will display the number of faults.
- Suitable for diameters range 0.05 up to 1.6 mm (44 -14 AWG).
- Test voltages adjustable in 8 steps: 350V, 500V, 750V, 1KV, 1.5KV, 2KV, 2.5KV, 3KV
