CMV Current Transformer Metering 0.6 kV
CMV: 600 volt, indoor or outdoor, 10 kV BIL, primary amperes: 100-4000, 25-60 Hz
CMV-S: 600 volt, indoor or outdoor, 10 kV BIL, primary amperes: 1000, 60 Hz, Class: 0.15S B-0.5 (IEEE 0.15S class metering accuracy)
CMV
The CMV transformer is designed for pad-mounted distribution transformer metering. It is available in two external designs, tapered bottom and wide bottom, for adaptability to a variety of mounting arrangements. Both designs can be mounted directly over the ILV terminals of pad mounted distribution transformers.
CMV-S
The CMV-S transformer is also designed for pad-mounted distribution transformer metering. It is designed for metering on 600 volt systems inside high ambient temperature environments up to 85ºC and can be mounted directly upon the energized busbar. A single 1000:5 ratio unit will perform at the 0.15S metering class from 50A - 2000A for extended range metering. The CMV-S is part of ABB’s AccuRange® current transformer portfolio, transformers that reduce inventory requirements and significantly improve metering accuracy.
