From 28th to 30th November 2023 representatives from OOO NPP Mars-Energo conducted an immersive training session for the customers from Electrical Testing Company (ETC) and Chan Hung Trading Technical Services Joint Stock Company in Ho Chi Minh City, Vietnam.

This specialized training took place at the heart of ETC's testing hub and was focused on the calibration of instrument transformers using the CT/VT Test Set manufactured by OOO NPP Mars-Energo and delivered to ETC earlier this year.

The purchased CT/VT Test Set was designed by OOO NPP Mars-Energo for the calibration of both traditional and low-power voltage and current measuring transformers and included the following instruments:

  • Multifunctional reference meter Energomonitor-61850
    •   Mobile High-Voltage Source MIN-220
    •   Capacitive High-Voltage Transducer CH VT220
    •   Adjustable current source IT 5000
  • Instrument current transformer TTI-5000
  • Burden Box MNTT
  • Burden Box MNTN

For over 25 years Mars Energo designs and manufactures equipment for the electrical power industry. All this time we focus our efforts on developing stationary and portable systems for accuracy testing, verification and calibration of electricity meters and instrument transformers.

At present, more emphasis is placed on developing reference instruments and test equipment used for commissioning and maintenance of digital substations. Another part of our research and development activities is devoted to instrument transformers based on optical technology.

We offer a variety of solutions for testing:
  • Electrical energy meters with analogue and digital inputs
  • Conventional instrument transformers
  • Non-conventional instrument transformers:
    •   Digital (with Sampled Value outputs according to IEC 61850-9-2LE)
    •   Electronic instrument transformers (low-power instrument transformers or LPITs) with either analogue or digital outputs.
