Higher current – wider test range!

RETOM-61 — based universal test set is an up-to-date solution for complicated diagnostic tasks. The set allows manual and automatic testing and debugging of all types of relay protection, from electromechanical panel to microprocessor terminals.

Flexibility in application:

  • internal microcomputer provides RETOM-61 operation with any Windows 2000/XP/Vista/Seven/8-operated PC;
  • Instrument/PC Ethernet link enhances communication speed and allows to control several RETOM-61 by one PC. Combination of 10 instruments in one set allows to carry out dynamic test and transients modeling using up to 60 current and 40 voltage channels;
  • two three-phase current systems permit easy and rapid test of transformer differential protection;
  • three-phase output current increased to 72 А, meanwhile power per channel is 1000 VA;
  • 200 A single-phase maximum output current allows to cover up to 90% of current settings used;
  • four voltage supply units allows to configure three-phase voltage system and 3U0 galvanically separated channel;
  • up to 405 V single-phase voltage permits to test 0,4 kV relay circuits;
  • frequency range increased to 1000 Hz;
  • a special DC voltage supply unit (=U) is provided to energize the device under test;
  • the device is equipped with full-function dual channel oscilloscope-multimeter;
  • internal high-resolution (0.1 ms) 16-input discrete analyzer allows to analyze response of the protection under test to the maximum;
  • 8 output relays allow to set any binary signal combinations for complicated protection systems test, IED in particular;
  • PC connection is made thru Ethernet port.


  • three-phase voltage system together with 3U0 channel permit to test complicated protections that need y-connection and open delta connection (or capacitive voltage transformer cubicle connection), auto-synchronizers etc.;
  • RЕТOM-61850 switching module permits to test IED protections according to IEC 61850 standard requirements;
  • RЕТ-64/32 module usage allows to increase number of binary inputs up to 80 and outputs up to 40;
  • using RЕТ-GPS modules it is possible to synchronize operation of two systems widely spaced apart which is a unique possibility to test simultaneously both OL protection subsystems located at its ends;
  • single-phase current transformer RЕТ-10 is designed for current scaling with 10, 6 and 0.1 ratios which permits to obtain valid current measurement from 1mA to 720A channel;
  • three-phase voltage transformer RЕТ-ТN is intended to scale voltage with 1/v3; 1; v3 and 5 ratios which allows to test relay protection and automation system for 0.4 and 0.66 kV, energy meter including;
  • all connectors are located on the front panel permitting to operate the device both in vertical and in horizontal position;
  • RЕТОМ-61internal microcomputer provides operation with any Windows XP/Vista/Seven/8-operated PC;
  • friendly and Windows-conventional interface;
  • free software suit permits in manual and semi-automatic mode and a special suit in automatic mode to test easily and rapidly any relay and protection.;
  • RЕТОМ-61 open control architecture allows user to create his own test programs with wide range of automation;
  • use of standard Windows facilities for preparation of protocols permits to facilitate report creation;
  • single PC-based parallel operation of several RЕТОМ-61 devices permits to obtain necessary number of current and voltage sources;
  • convenient way of software updating allows to use the latest version;
  • joint operation with RЕТОМ-VCH enables user to carry out full-scale test of instantaneous carrier-pilot phase comparison protection subsystem.

Safety and reliability:

  • IED with a wide-range internal monitoring provides high safety both for the device itself and for equipment under test;
  • in case of emergency all output signals are switched off and test process is stopped until recovery. This essentially increases security of test works and verification of the data;
  • analog input isolation provides secure measurement of external voltages;
  • channel accident-free terminals provide protection against electric shock;
  • safety operation within a wide range of line voltage;
  • robust and aesthetically pleasing device case is resistant to mechanical impacts.
