AC HV Spark Tester

Rectifiers & Electronics, an ISO 9001: 2008 company, offers AC HV Spark Tester. These high voltage spark testers are designed for checking the quality of PVC coated wires during manufacturing at shop floor. The PVC wire is passed through brass ball chains, which carry high voltage. If any pinhole comes in PVC, a spark develops and electro-magnetic counter counts the fault. The spark tester in necessary for every cable manufacturing unit. These spark testers up to 15 kV are cooled, thereafter transformer is oil immersed and control panel air cooled. Control – knob to control the AC output from zero to maximum; protection – (a) On-Off switch with fuse provided to protect the unit of case in shot circuit, (b) HV will not actuate unless variac is at zero position, and (c) The HV trips off automatically if anybody trips to each ball chain; fault indicators – audio alarm is provided to indicate fault which passes through ball chain; fault counters – an electro-magnetic counter is provided to count the faults with resetting knob; and optional – (1) Guide rollers with strong frame, (2) Tripping circuit to cut of the HT supply in case of faulty, (3) Sensitivity control, (4) Sensitivity checking device, (5) Stainless steel electrode box and (6) Digital metering.
