EM4900 Installation: Using Voltage/Potential Transformers

User may need to use PTs when installing the EM4900 series meters and may not know that they do NOT have the option to program PT ratios in their configurations.

Product Line


BCPM and EM4900 series meters do not have the option to program PT ratios in their configurations.

The user may use PTs to step down the input control power and measurement voltages as required, but will need to compensate for the ratios when reading the meter's outputs, in the case of the measurement voltages.
For example, if a PT of ratio 480:120 is used, one will need to multiply all the output values, with the exception of the current, by a factor of 4.

Kindly refer to the link below for the EM4900 series documentation:
