• Efficient and proper testing of meters in minimum duration. To achieve this objective, each aspect of meter testing should be taken care e.g. process optimization, quick connection of meter, multi-functional testing, data administration.
  • Accuracy testing of instrument transformer (ratio and phase angle errors)
  • On-line Testing at Consumer Load: In this method the tester connects the reference meter to the meter under test, i.e. voltage in parallel and current in series using clamp on CT. This is a quick & economic method but tester has to rely on running consumer load. The objective of such testing is to check the connection and any existing tamper condition and to get a fair idea of the accuracy of the installation.
