RЕТОМ-61

РЕТОМ-61 relay protection and automation test system

R&D “Dynamica”, designer and manufacturer of state-of-art test systems of RETOM family, produces in lot RЕТОМ-61-based multipurpose test system RЕТОМ-61.

RЕТОМ-61 basic advantages

New possibilities:

• internal microcomputer provides RETOM-61 operation with any Windows 2000/XP/Vista/Seven-operated PC;
• two three-phase current systems permit easy and rapid test of transformer differential protection;
• three-phase output current increased to 30 А, meanwhile power per channel is 500 VA;
• 90A 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 405V single-phase voltage permits to test 0.4kV 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) 32-input discrete analyzer allows to analyze response of the protection under test to the maximum;
• 24 output relays allow to set any binary signal combinations for complicated protection systems test, IED in particular;
• PC connection is made thru USB, COM ports.

Serviceability:

• 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.;
• RЕТ-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 96 and outputs up to 56;
• 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, e.g. ДФЗ-201(instantaneous carrier-pilot phase comparison protection);
• 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 300A 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-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-VCHm 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.
