RETOM-51 (РЕТОМ-51) – power in your hands!

Reliability of relay protection equipment is mostly determined by quality of its performance check both in debugging and in field operation. These checks are carried out on a regular basis using specific tools generating currents and voltages necessary to diagnose Relay Protection and Automation equipment.

As utilities have a great number of relay units their testing requires significant expenditure and high skilled personnel. Test system based on RETOM-51 instrument would be of great help to cope with this problem.

Application:

  • universal three-phase current and voltage source providing that each parameter can be amplitude and phase controlled,
  • test system for relay protection and automation testing under debugging and commissioning, followed by test protocol,
  • universal wide range current, voltage and frequency measuring tool.

 

  • automated testing and adjustment of all generation relay protection and automation devices,
  • up-to-date microprocessor-based relay and complicated home and foreign protection systems,
  • solid-state relay protection and automation systems,
  • whole range of relay protection and automation electromechanical panels and sets,
  • home and foreign fault locators,
  • emergency control panels and remote measurement circuits,
  • synchronizing devices,
  • watthour meters,
  • generator excitation system,
  • railway protection systems.

Main advantages:

  • free standard multifunctional software package allows easy and quick manual and semiautomatic (special package for automatic) test of any relay and protection,
  • joint operation with RETOM-CVHM set allows full test of phase differential protection subset,
  • using RET-GPS units it is possible to arrange synchronized operation of remote two sets providing unique opportunity to end-to-end test of differential phase protection subsets,
  • wide range built-in intelligent device provides high safety as of the instrument as the equipment under test,
  • in case of disturbance all output signals are tripped and testing procedure is suspended until troubleshooting. This considerably improves safety work and accuracy of the results,
  • reliable operation in a wide network range,
  • user-friendly and well-familiar Windows interface,
  • the open control architecture of RETOM-51 ensures quick and simple development of individual testing programs,
  • a solid and a good-looking case, considerably more resistant to mechanical influence,
