1. General
The outdoor metering unit of type RBM are intended for outdoor installation for metering power grid. The products mainly consists two parts, combined transformers and watt-hour meter there. The former is made up to two or three single-phase voltage transformer and current transformer, which adopts 25# transformer special oil as insulation medium and whose primary and secondary line ends are both installed one panel by porcelain bushing.
Watt-hour meter tank is fixed on the flank of combined transformer and comprises one active metering meter and reactive KWH meter, which has high precision measurement, light weight, convenient and low lose functions.
This outdoor power metering unit is applicable to 3 phase and 50Hz, 6kV up to 40.5kV power grid.
The products are widely compliance with relating IEC/ANSI international standard.
