CURRENT CIRCUIT:

Loading Transformer:

Double winding loading transformer of suitable burden to provide corresponding current output specified before.

Measuring CT:

Multi-ratio wound primary current transformer. Ratio: 2-20-200A / 2A.

Variable Autotransformer:

For smooth variation of current output at various ranges selected.

Protection: The current output would be cutoff in case of any overload or even if the relay under test actuates.

Metering: Direct reading with meter range selector.

AC VOLTAGE CIRCUIT:

For smooth variation of voltage output from 0 to 250 volts AC at 1Amps.

Metering: Digital, Range: 0 to 250V AC.

DC VOLTAGE CIRCUIT:

Separate DC voltage source with ON/OFF switch, fuse & lamp indication.

For smooth variation of voltage output from 0 to 240 volts DC at 0.5 Amps.

Isolation transformer of suitable burden is provided for DC output.

Metering: Digital, Range: 0 to 250V DC.

Provision for the Timer contact for checking protective equipment like breaker/Relay tripping.

Time Interval Meter (TIM):

Microcontroller based 8 digits Timer.

Range: 0 - 9999.9999 seconds with minimum count of 0.1 milli seconds. Accuracy 0.05%.

The Timer will be capable to record & display the tripping time of relay under test automatically.

The Time Interval meter will be suitable to measure Closing (Make) and Opening (Break) time for Relay through Potential Free contacts.

The TIM will be provided with Rest facility.

Precision and Versatility for Protective Relay Testing

The PSRNT200FC relay test set provides versatile current output selections (2A to 200A) through heavy-duty terminals. Its digital display and timer facilitate precise control and monitoring, while robust overload protection safeguards equipment during testing. Designed for accurate measurements and safe handling, this compact yet rugged device is well-suited for testing a variety of protective relays in power distribution and industrial settings.


Easy Operation and Reliable Safety Features

This test set combines ease of use with advanced safety features, such as an insulation box and LED ON/OFF indicators. The digital timer's simple start/stop mechanism, overcurrent and earth fault protection, and thermal cut-out contribute to operator safety and unit durability. Its corrosion-resistant housing and air cooled design ensure longevity and minimal maintenance.
