Wire And Cable Spark Tester High Voltage 0~40c° Continuous Operation
Description:
Frequency AC Spark Tester is a special-purpose test apparatus to detect fault of insulation on wire and cable. Integrated with the technology of solid-state AC voltage regulation and single piece microprocessor control, the machine features steady voltage output (unaffected by variation of supply voltage), high sensitivity of fault detection, versatility, user-friendliness, safety and reliability, new construction and beautiful appearance.
The work principle of the spark tester is as follows: Make the tested wire pr cable travel through the high voltage bead-chain electrode having test potential supplied by a commercial frequency HV transformer. If the insulation has fault, breakdown will occur, namely the output of the HV transformer will cause a HV spark short-circuit. The short circuit current flows from the output terminal of the HV transformer through insulation fault-conductor of cable-earth-ground-HV transformer to form a circuit.
Therefor both the spark tester and the conductor of cable shall be soundly earth-grounded otherwise the short circuit cannot be formed and the cabinet of the spark tester and conductor of cable may have high voltage.
