RЕТОМ-21

RЕТОМ-21-based multi-purpose system for primary and secondary equipment test

New RЕТОМ-21-based test system is a mobile, multi-purpose, powerful tool.

In a lot of ways electric equipment reliability is defined by testing the quality of its on-site parameters. It takes much time for power engineers to provide maintenance of various primary and secondary electric equipment often different in functions and which as well can be located at different premises of power utility.

Mobility, multifunctionality, reasonable currents and voltages at acceptable power, possibility to control phase angle between two sources, internal auxiliary current source, easy servicing, up-to-date automation facilities, accuracy – this is not-exhaustive list of basic requirements for testing equipment. РЕТОМ-21-based new test system by NPP (R&D works) “Dynamica” meets all these requirements to the full extent.

All constituent instruments of the system are certified.

Application.

RЕТОМ-21 test system is designed to test primary and secondary electric equipment at commissioning and on-site in the following branches of industry:

• power engineering;
• oil and gas;
• railway sector;
• enterprise utilities.

RЕТОМ-21 test system makeup.

RЕТОМ-21 test system apart from RЕТОМ-21 test instrument can include:

• RЕТ-3000 loading transformer;
• RЕТ-ВАХ-2000 instrument-transformer module and/or РЕТОМ-6000 insulation test device;*
• СПП-80mobile instrumentation rack;
• RЕТОМЕТR phase-volt-ampere meter;
• heady-duty case for RЕТОМ-21 transportation .

* — RЕТОМ-6000 use permits to obtain up to 6000V output voltage, moreover it allows to carry out full-scale insulation test with leakage current control and to test any type instrument and power transformers. It should be noted that RЕТОМ-6000 operates off-line.

Using RЕТ-ВАХ-2000 module having smaller dimension-weight characteristics in comparison with RЕТОМ-6000 device allows to obtain maximum 2000V output voltage but the block operates only with RЕТОМ-21 device.

Common use of RЕТОМ-6000 device and RЕТ-ВАХ-2000 block permits to obtain advantages of the two previous variants depending on the type of test.

Application and scope of test:

• relay, conventional and microprocessor protection,
• low-voltage control devices, contactors and magnetic starters,
• instrument current transformer,
• instrument voltage transformer,
• automatic circuit breakers,
• customer electric equipment and installation insulation test by overvoltage,
• measurements using RETOMETR (РЕТОМЕТРА)

RЕТОМ-21: decided step forward

RЕТОМ-21 test device is a base for a test system designed to check primary and secondary electric equipment.

In comparison with its predecessor device RЕТОМ-11М it has a number of essential advantages:

maximum output current is increased to 800 А;

• maximum output voltage is increased to 500 V;
• continuous and maximum output capacity have been increased to 2200 and 4200 VA respectively;
• possibility to control current, frequency, phase (angle);
• multimeter permits to measure current, frequency, phase;
• auxiliary power supply source is added;
• possibility to carry out full-scale current transformer test etc.

These RЕТОМ-21 advantages have resulted in possibility to expand the range of the tested equipment by the test system.

SЕТОМ-21 is a certified measuring facility.
