ekorRPT

Protection, Metering and Control Unit, used with functions for transformer protection. It contributes to the fuse protection with over current and low value phase to earth faults protection. It is self powered through current transformers, software configurable and communicable with history logs.

Technical Features:

• Power Range: 50 kVA-2500 KVA
• Protection Functions:
  • Over current
    • Phase over current (3X50/51)
    • Earth faults (50N/51N)
    • Sensitive earth faults (50Ns/51Ns)
  • External Trip: Protection function (49T)
  • Earth fault detection from 0,5 A
  • Switch-disconector trip blocking: 300A-1200A
  • Avoids any dangerous melting of the fuses (I3 Zone)
  • Possibility of testing primary and secondary of current transformers
• Communications (RS-485) and programming software (RS-232)
• History logs
• Current and zero sequence measurements Io, I1, I2, I3
• Self powered from 5A in one phase
• Optional integrated control (Auxiliary power supply)
