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 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 can be purchased as a Class 0.2S or Class 0.5S accuracy meter. The Mk3 includes support for optical fibre meter to meter communications; and support for quality of supply features such as harmonic analysis, voltage sag and swell logging.
