TESTING OF PROTECTION RELAYS:
EMC is actively involved in the testing of protection relays through direct orders and also through tender process.
We test protection relays (NUMERICAL AND ELECTRO MECHANICAL) of the under mentioned categories:
• Over Current
• Earth Fault
• Over Voltage
• Under Voltage
• Frequency based
• Power Factor based
• Fuse protection
• Auxiliary
• Time based
• Motor Protection
• Transformer Protection
• Differential and many more of single phase, three phase and poly-phase variety. Our universal Relay Test Kit from ISA (Italy) enables us to calibrate relays of all famous brands like:
• ENGLISH ELECTRIC
• SHNEIDER
• ALSTHOM
• AREVA
• MICOM
• MOTPRO
• L&T
• SIEMENS and many more.
