There are two procedures for doing the calibration of Surge Tester:
Pre-requisites for Calibration:
Calibrated Oscilloscope (Min 50MHz)
A balanced 3φ stator or two 1φ balanced coils
- Any Standard 50MHz or above Oscilloscope and X1000 times, 10KV AC Probe.
- Any Standard 50MHz or above Oscilloscope and X10 times AC Probe.
NOTE: The Oscilloscope can also be calibrated using a square wave generator
having a rise time of 0.1 micro sec, min. output voltage of 100 volts (peak-to-peak) and
frequency of oscillation of 1KHz.
