Overcurrent And Earth Fault Relay Manufacturer,Supplier and Exporter in India

• The relay module is based on the Micom P122 industrial relay. 
• They can also use the relay support software and a suitable computer to program the relay module. 
• The relay module is then connected to the fault circuits so tests can be performed. 
• The lecturer or student sets up different fault circuits on the Protection and Relay Test Set. 
• They then use the keypad and display on the relay module to program it to the settings needed for the tests. 
• Most tests are performed using single relays. 

The main functions of the Overcurrent and Earth Fault Relay include:

• Three-phase earth and overcurrent: three independent stages. 
• The first stage selectable from any of 12 IDMT curves.
• The remaining stages having a direct time characteristic.
• High impedance restricted earth fault.
• Thermal overload protection.
• Negative-phase sequence overcurrent: two independent stages.
• Broken conductor detection.
• Selectable blocking, Undercurrent.
• Trend, fault and disturbance records.
• Circuit monitoring.
