MTS-50 Meter Test System

Phase: 3
AC voltage output: 0-792V
AC current output: 0-60A
Accuracy: 0.05%RG (Class 0.05) or 0.1% RG (Class 0.1)
This meter test equipment 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.

Description

  • Calibrate all kind of single/three phase electronic/inductive active and reactive energy meter
  • 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
  • Support variables influencetests, such as: Voltage, frequency, harmonics, reverse phase sequence, Voltage unbalance, etc
  • Support special tests in energy meter type test, such as: phase triggering, pulse train triggering, etc
  • 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.
  • With OCXO, daily error of energy meter can be detected
  • Output 2nd~63rd harmonics
  • 8” TFT screen, interface friendly, easy to operate;
  • Equipped with RS232, Ethernet, and WiFi interface,MTS-50 can either support stand-alone operation, PC control or handy wireless terminal control;
  • Communicate with tested meters thru RS-485;
  • Automatically calculate the error of meter, and the related data can be downloaded thru U-disk;
  • Self-protection, alarming and displaying overload location for equipment output overload, Voltage short-circuit, Current open-circuit;
  • Automatically detect, diagnose and alarm for failure.
  • Remotely updating online, easily achieve software updating;
  • Support calibration by user locally
