RETOM-25 is a new system in RETOM product range, which has all the functionality of RETOM-21, but is light in weight (19 kg) and compact (340х430х205 mm).

Application

RETOM-25 is irreplaceable for test and adjustment of the following primary and secondary equipment:

  • all types of electro-mechanical relays (directional and non-directional current relays, voltage, resistance, power, frequency, time, indication, auxiliary and other relays),
  • micro-processor protections 6-10-35 kV,
  • residual current circuit-breakers,
  • measuring current transformers,
  • measuring voltage transformers,
  • grounding equipment,
  • auto-reclosers,
  • high-voltage circuit-breakers,
  • automatic circuit-breakers,
  • low-voltage control devices,
  • contactors, electromagnetic actuators, etc.

Main advantages:

  • max. output current of 200 A – enables tests of all relay types, measuring of transformation ratio and polarity of current transformers;
  • max. power of 5000 VA – output power of the device for operation with additional modules RET-3000 and RET-VAH-2000;
  • output voltage of 250 V – operation in 220 V networks, taking volt-ampere characteristics of measuring current transformers with saturation voltage of 250 V;
  • compact and convenient in use – device can be easily transported thanks to its low weight (19 kg only) and small dimensions, removable cover enables its use both in vertical and horizontal position;
  • expansion of device functionality by using  RET-3000 loading transformer, RET-DT current converter, RET-VAH-2000 transformer module, RETOM-6000 insulation tester, RETOMETR-M2 volt-ampere-phase-meter;
  • accurate measurements – available electronic controller enables setting values of output parameters with small step (0.1% of selected range), which ensures obtaining more accurate measurement results. Additional indicators enable determining of controller current position;
  • a wide range of measurements of delivered and external current, voltage, frequency, phase angle, all types of time characteristics (operation, reset, duration, time diversity, bounce) of different relays and switching devices, determination of impedance, resistance and reactance, apparent, active and reactive power;
  • various measuring methods: based on amplitude, half-period average value, true RMS, with first harmonic distinguishing (50 Hz);
  • phase and frequency control: capability of controlling phase angle between two sources enables test of directional protections (power relays, resistance relays, etc.), as well as synchronization systems;
  • capability of frequency variation within a wide range (20-1000 Hz) enables test of filter relays, high setting accuracy (0.001 Hz) enables test of frequency relays, while frequency variation rate control (df/dt) enables AFLS and FAR test;
  • auxiliary power supply source (220 W) enables test of RPA devices in autonomous mode at rated, reduced and increased voltages (176 - 260 V);
  • computer control – device can operate both in autonomous mode and under PC control. Software included into the delivery kit contains “Manual control” module for fully functional control of RETOM-25 basic components, as well as automatic test programs for most relay types (current, voltage, power, frequency relays) and taking volt-ampere characteristics of measuring current transformers;
  • verification interval of 4 years.
