The Design

The Portable Meter Test System is designed to carry out meter testing at the site and in the laboratory as specified in the IEC and IS. It consists of

  • Three-phase reference standard of accuracy class 0.04 /0.1
  • Three-phase integrated voltage and current source up to 3x 600 V /120 Amp
    It can be used as a reference standard or source or combination of both

    Application

  • Testing of electricity meters according to IEC and IS directly on-site including accuracy test, register test, demand testing and various influence quantity tests
  • Verification of wiring
  • Measuring and recording of power quality parameters
  • Testing of CT for ratio and phase angle error as per IEC and IS
  • Burden measurement of CT and VT
  • Functions and Features

    TS33- as a Reference Meter- Power Network and Power Quality Meter

  • measurement of power network parameters (such as voltage, current, frequency, various phase angle & PF, Powers (Active, reactive and Apparent) approx 41 parameters)
  • Visualization of measurement results in form of table, vectors, trend chart, Oscilloscope (waveform) or bar chart
  • Testing of various type of energy meters (1P2W, 3P3W, 3P4W--for active reactive and apparent energy using scanning head

    TS33- as a three-phase source

    The TS33 power calibrator can work in two modes:
  • voltage and current source
  • current source synchronised with the input voltage. Refer to the technical specification for generation parameters

    TS33 as an Automatic Meter Tester

    in this case, the TS33 is used as a test system with reference meter and integrated voltage and current source in manual or automatic operation mode with predefined (voltage and current) load points.
    with using following functions
  • calculating meter error (partial errors, average error, standard deviation) directly in [%] with method of settings time of measurement or number of pulses,
  • measuring energy for verification of meter counters directly in [%],
  • maximum power measuring for testing of maximum power meters,
  • for different kind of measuring powers P, P+, P-, Q, Q+, Q-, S, as well as for the first harmonic of these powers
  • with visualization in form of table or trend chart.
