Q PMU-9 Phasor measurement unit (PMU)
Small PMU for one or two circuits
A substation hardened PMU for connection to one or two three phase circuits to calculate and stream phasors in compliance to the IEEE C37.118 specification.
- Full compliance to IEEE C37.118
- Ideal for use when a multifunction device cannot be justified
- Digital status included in data stream to log circuit breaker positions
- Web page configuration
- 32 digital channels - wide ranging input from 48 to 250V DC (24 to 250 VDC optional)
Multiple PMUs at different points on a transmission system send phasor data to a central phasor data concentrator (PDC) where separate analysis software monitors system stability parameters and warns of impending problems so that remedial action can be taken to avoid blackouts.
