Current and Voltage Transformer Testing and Commissioning

Instrument transformers feed protection and metering systems, so errors in current and voltage transformers ripple through the whole substation. This course gives delegates the skills to test, verify and commission these devices correctly. It supports reliable protection and accurate revenue metering for African utilities and industry.

What you will be able to do

  • Explain the role and construction of current and voltage transformers
  • Interpret accuracy classes, ratios and burden requirements
  • Perform ratio, polarity and insulation tests
  • Verify magnetisation and saturation characteristics
  • Commission instrument transformers into protection and metering circuits
  • Diagnose common instrument transformer faults
