Spark Tester Calibrator

For Spark Testing with constant and comparable sensitivity on insulating, winding and sheathing lines, it is very essential to calibrate the spark tester with a spark tester calibrator.

KAT Controls make Spark Tester Calibrator Model STCAL-2K is designed to meet the requirements of relevant Indian and international standards for Spark Testers. One can measure the test voltage and it’s frequency with the help of Spark Tester Calibrator.

Incorporating Digital Voltmeter, this versatile Calibrator is used for both Voltage Calibration and measurement of Fault detection sensitivity of various makes and type of spark testers.

Measurement and display circuits for :

  • Test Voltages up to 15 kV RMS for AC High Frequency Spark Testers
  • 30 kV RMS / DC for AC Mains Frequency / DC Spark Testers resp
  • Test Voltage Frequency upto 4000 Hz

Artificial fault device

  • Checks the sensitivity to ‘faults’ according to IS:10810 (part 44) – 1984, BSEN 50356:2002
