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.
Work conditions

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
