High-voltage metrological mobile lab rated at 6÷330 kV, 50 A ÷ 5 kA




  • Testing of instrument voltage transformers (VTs) rated from 6 to 330 kV
  • Testing of instrument current transformers (CTs) up to 5 kA or up to 30 kA
  • Testing of electric energy meters
  • Testing of channels within automatic metering and billing systems
  • CT and VT burden measurements
  • Determining voltage drops in secondary circuits of VTs
  • Determining basic power quality parameters (PQP), as defined by IEC 61000-4-30

MarsLab-CT/VT can contain the following sets:

  • CT test kit
  • VT test kit up to 10 kV (HTCS)
  • VT test kit up to 330 kV (HSCS)
  • Test kit for electric energy meters and power quality analyzers

MarsLab-CT/VT equipment consists of individual units on frames, each enclosed in its protective plastic cabinet.
Design advantages:

  • The units are designed for transportation in the equipment bay of a vehicle
  • The units can be easily taken from the vehicle and connected for testing (two persons can cope with the task)

Note! We offer various training programmes for users of Mars-Energo instruments and software.
