Features
The salient features of Trip Circuit Supervision Relay are:Fitted with flush-mounting
  • Continuous supervision of trip circuit in Pre-closed, Post-closed condition, and latched trip condition
  • Detects faults such as Auxiliary voltage loss and circuit breakage in supervised circuits
  • Indicates operational status by single LED with dual color
  • Relay has been type tested in accordance with IEC60255 standards


Applications:
  • Trip Circuit Supervision Relay is used in the following fieldapplications:
  • Used for monitoring activities. The trip circuit wiringis supervised from the positive supply to the negativesupply when the circuit breaker is in open position orclosed position.
  • Used for detecting and generating circuit breaker alarm,if the trip circuit supply is failed.
  • Used to generate an alarm if the trip signal is receivedbut the circuit breaker fails to operate.

7SR110 Argus Relay, Siemens Numerical Relay, Siemens Over Current Earth Fault Relays

The 7SR11 series of relays provide overcurrent and earth fault protection. These relays are typically applied to provide the main protection on feeders and interconnectors and the back-up protection on items of plant such as transformers. On distribution system circuits overcurrent and earth fault protection is often the only protection installed.

The 7SR12 includes for directional control of the overcurrent and earth fault functionality and is typically installed where fault current can flow in either direction i.e. on interconnected systems.

The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protections.

The relays are available in single and four pole variants housed in E4 cases with the IEC61850 protocol option housed in an E6 case. Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue inputs and binary input/output circuits.

Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection or rear electrical RS485 port for remote connection are provided.
