Relay Protection Parameter Measuring Device RETOM-21.3 for Autonomous Testing

The RETOM-21.3 device is fully autonomous and does not require connection of a personal computer. The device is an electronic device for checking all parameters of 0,4-10-35 kV relay protection devices, including 6-10 kV cells with microprocessor protection, all types of simple relays and protections (current, voltage, frequency, time, indicating, intermediate, etc.) and other electrical equipment in relay protection schemes.
