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.
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.
Work conditions Supply voltage: AC220V±10% Supply frequency: 50±2Hz Ambient temperatures: 0~40c° Relative humidity, max: 85% (without condensed water) Mode of operation: continuous operation Breakdown indication Mode of indication: Breakdown count and voice/light alarm Count range: 0~999 Time duration for voice/light alarm:0.5-15adhustable Safety interlock In order to ensure safety for operators, the probe is provided with an interlock switch and a discharge rod .When the front hood is opened, the high voltage is cut off first, then the discharge rod touches the electrode section to discharge the remaining electricity Technical Parameter
