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.
