Mk3
- Class 0.2S / Class 0.5S Energy Meter
The Mk3 revenue meter is high accuracy meter with
extensive in built features for the deregulated market.
It is available as a whole current (100A) meter or a CT
connected unit (1A or 5A). Each meter is capable of
four-quadrant measurement of one three-phase load. It
conforms to IEC 60687 and IEC 61036 Class 0.2S accuracy
and includes support for fibre meter to meter
communications and meter-side harmonic analysis and
logging.
