Representative: Ramaswami Bharath

ERLPhase Power Technologies is an ISO 9001:2008 QMS certified manufacturer of digital fault recording systems and protective relays.

All ERLPhase relays are easy-to-use with intuitive software, and are built on a substation-hardened platform to provide reliable protection and high-quality recording.

Our relay family includes:

  • B-PRO bus protection
  • F-PRO distribution protection/management
  • L-PRO line protection
  • S-PRO sub-harmonic protection
  • T-PRO transformer protection

Our newest line of relays, the 4000 series, all include IEC 61850 station bus communications.

ERLPhase digital fault recorders, named “TESLAs”, have proven to be very popular in the industry. TESLA multi-timeframe power system recorders have non-volatile on-board flash memory and remote input modules to cost effectively record disturbances, while also providing PMU (Phasor Measurement Unit) and CDR capability that exceeds NERC standards.

ERLPhase Power Technologies is based in Canada and is a wholly-owned subsidiary of Easun Reyrolle Ltd.
