The new KoCoS METES 340 REF three phase revenue meter test system, available from Westek Electronics , is suitable for testing and calibration of revenue meters.
The METES 340 REF has voltage inputs to 480V AC and direct current inputs to 120Amps AC and current clamps for larger currents.
Six pulse outputs proportional to energy are provided as well as 4 binary inputs with a trigger range of 24 to 300 Volts DC. Remote connectivity is available via ethernet, RS232, USB and EPOS 300 interlink and the GPS receiver permits precise localisation of revenue meters.
The KoCoS METES 340 REF measures a large number of power quality parameters including DC content, harmonics and flicker analysis. The instrument also provides a full suite of line parameters including power, apparent power and energy including phase angle, power factor, and frequency. The instruments are operated via a membrane keypad and are provided with large LCDs.
