IDMT And Directional Over Current Relay Setup Manufacturer,Supplier and Exporter in India
Product Code : ILS-EELE-10405
Indian Lab Suppliers supplies the IDMT And Directional Over Current Relay Setup (Product ID: 10405) as part of its electronics engineering lab equipment range. It is a test set-up for plotting the time-current characteristics of IDMT and directional overcurrent relays.
Quick Answer
An IDMT (inverse definite minimum time) relay trips faster as fault current rises, down to a fixed minimum time; a directional unit operates only when fault power flows in the set direction. A phantom fault is produced with a continuously variable autotransformer and a current limiter, and a digital voltmeter, digital ammeter and digital start/stop time interval meter record the current and operating time. The supply is switched through a built-in MCB, and power-on and trip-status indicators are fitted. Please confirm at quotation whether an electromechanical or a numerical (digital) relay is required.

Frequently Asked Questions
What does IDMT mean?
Inverse definite minimum time: higher current, shorter trip time, down to a set minimum.
What does the directional unit add?
It trips only for faults with power flowing in the set direction.
How is trip time measured?
With the built-in digital start/stop time interval meter.
