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.

• 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.
