- Documents (certificates)
RETOM 21 is designed for adjustment of secondary electrical equipment in relay protection circuits and allows to perform some tests of measuring current and voltage transformers, low-voltage devices and power switches RETOM-21 is used for testing and adjustment - of all types of electromechanical relays (directional and non-directional current relays, voltage relays, resistance, power, frequency, time, indicating, intermediate, etc.); - of microprocessor protections 6-10-35 kV; - of automatic Restart; - of measuring current transformers; - of measuring voltage transformers; - of grounding; - of automatic reclosing; - of high-voltage switches; - of circuit breakers; - of low-voltage control devices; - of contactors, electromagnetic starters, etc.
Retom-21 is a test device for checking primary and secondary electrical equipment. It is used during the initial commissioning of equipment and during regular checks during operation. It is used in electric power plants, in energy facilities of manufacturing enterprises.
- maximum output current 700 A;
- maximum output voltage 500 V;
- maximum continuous and maximum short-term output power - 2,000 VA and 6,000 VA, respectively;
- output of adjustable direct (rectified or smoothed) voltage up to 350 V and current up to 8 A;
- the ability to adjust current, frequency, phase (angle);
- the built-in multimeter allows you to measure current, frequency, phase;
- measurement of all types of time characteristics of various relay switching devices in the range of 0.0001 - 10,000 s;
- frequency regulation with a minimum step of 1 MHz in the range of 20 - 1000 Hz;
- control of the frequency change rate, which allows you to check the automatic frequency shifter and automatic reclosing system;
- the electronic controller allows you to set the values of the output parameters in 0.1% increments, which ensures more accurate measurement results;
- additional indicators make it possible to track the change step in the range of 0-100%;
- an operational power source (220 W) allows you to test the relay protection and automation devices in an autonomous mode at nominal low and high voltage (176-264 V);
- reproduction of a controlled discrete signal (imitation of the "RPV" and "RPO" contacts or an acceleration signal);
- the ability to output current and voltage in long-term, single and pulse modes, which allows you to test the relay protection and automation devices taking into account their selective operation;
- determination of the polarity of the CT and VT windings;
- measurement of the transformation ratio;
- measurement of the apparent, active and reactive power, as well as the efficiency. – cosφ and losses – tgφ;
- measurement of the total, active and reactive resistance of the connected load, starting from 0.1 mOhm;
- the ability to fully test current transformers, etc.
- it is possible to work both in autonomous mode and completely under computer control;
- the software module "Manual control", included in the device software, duplicates all the controls of RETOM-21 and allows you to display in one window significantly more measured parameters than on the device display, which makes the work even more convenient;
- programs for automatic testing of most types of relays and removing the I-V characteristics of measuring CTs;
- the use of additional units RET-3000, RET-VAH-2000, RETOM-6000, RETOMETR-M2, RET-MICRO significantly expands the capabilities of the RETOM-21 device;
- due to the impact-resistant plastic body with built-in rollers and a retractable handle, the RETOM-21 can be easily transported to the test site.
