Procedure for testing the meters on line

  The single or three phase meters installed and commissioned at site are tested online i.e. without disconnecting the lines of the meter under test. The inputs to the testing unit, such as the voltage signal is taken from the test terminal Block (TTB), the current signal is taken through external clamp on type Current Transformers (CTs) connected on outgoing lines and the sensor unit is used for pulse counting of the meter under test. The series of tests are conducted to obtain the percentage error of energy measurement as well as the dial readings.
