This Meter Test System features state-of-art designing with high accuracy. It is composed of high accurate (class 0.05% or 0.1%) standard reference meter and power source (up to 50A). This system is particularly designed with modular structure for calibration and test of different single phase/3 phase electronic/inductive active and reactive energy meters.
It is operated under high functionality with user friendly interface.
Main function:
s Calibrate all kind of single/three phase electronic/inductive active and reactive energy meter
s Automatically or single-step manually test basic error, creeping, starting, standard deviation of single/three phase energy meter, save user-defined calibrating scheme in Auto calibration
s Support variables influence tests, such as: Voltage, frequency, harmonics, reverse phase sequence, Voltage unbalance, etc
s Support special tests in energy meter type test, such as: phase triggering, pulse train triggering, etc
s Support DLT-645 communication protocol,multi-testing of multifunction meter such as: demand indication error, demand cycle error, time slot switching error, energy error of different tariff period, etc.
s With OCXO, daily error of energy meter can be detected
s Output 2nd ~63rd harmonics
