Typical Applications
The M100-XA series measure reactive power in single, 3 phase 3 or 4 wire balanced and unbalanced systems. Using the time division multiplier circuit means that they can be used over a wide range of input waveforms. The D.C. output signal is directly proportional to the instantaneous reactive power being measured.
Typical Applications include the measurement of reactive power in switchboards, power stations and generating sets etc. The high isolation of 4kV as with all M100 series allows these transducers to be connected to a variety of measuring and control devices and systems, such as analogue meters, PLC, computer systems, data loggers, digital instruments and telemetry systems.
Both auxiliary powered and self powered versions of each type are available. It is recommended to use an auxiliary powered version if the system being measured has voltage variations in excess of ±20%
