Ac High Voltage Spark Tester


Ac High Voltage Spark Tester


We bring forth high end AC High Voltage Spark Testers. Our AC High Voltage Spark Testers are meant to check the quality of PVC coated wires during manufacturing process. Here, the PVC wire is made to pass through brass ball chains that carry high voltage. If any pin hole comes in PVC, a spark occurs and electromagnetic counter counts the fault. This AC High Voltage Spark Testers is essential for every cable manufacturing unit.

The AC High Voltage Spark Testers uses a high frequency oscillator circuit for increasing frequency to look for the fault at low leakage current and signifies that as a fault which is displayed to the operator through a visual and audible indicator. Our AC High Voltage Spark Testers can test a number of cables at various voltages for which KV setting & sensitivity setting is given.

Transformer A double wound step up transformer is the most important part of the spark tester. The transformer is so designed that the input current remains within set limit in order to protect the transformer against short circuit. The transformer is made of CRGO core, wound with very high quality super enameled copper wire and polyester film/paper is used for insulation. VOLTAGE Control A step-less auto-transformer is used for controlling the output form zero to maximum. The auto transformer has built in arrangement for zero start interlocking. INPUT Voltage 230 Volts single phase 50Hz. AC Supply Output Voltage Up to 40 KV CAPACITY : Up to 5 KVA Metering Voltmeter is provided in L.T. side, to indicate HV Output Electrode Brass ball chain electrode is having a number of balls to ensure 100% contact with the coated wire which passes through the electrodes. Control Knob to control the AC output from zero to maximum. Protection (a) On-Off switch with fuse provided to protect the unit in case of short circuit. HV will not actuate unless variance is at zero position.
(b) The HV trips off automatically if anybody tries to reach ball chain. Fault Indicators Audio Alarm is provided to indicate fault which passes through ball chain. Fault Counter An electro-magnetic counter is provided to count the faults with resetting knob. Electrode Box (a) Length-450mm or 600mm or 900mm
(b) Height Adjustable anywhere from 600-1000mm from ground level Optional (a) Guide Rollers with strong frame.
(b) Tripping circuit to cut off the HT supply in case of faulty cable/bare conductor passing through electrode.
(b) Sensitivity control
(c) Sensitivity checking device.
(d) Stainless steel Electrode Box
