Relay Protection Clause Samples
The Relay Protection clause establishes requirements and standards for the installation, maintenance, and operation of protective relay systems within an electrical network. It typically outlines the responsibilities of parties to ensure that relays are properly set, tested, and coordinated to detect faults and isolate affected sections of the system, thereby preventing equipment damage and ensuring safety. By clearly defining these obligations, the clause helps minimize the risk of widespread outages and equipment failures, ensuring reliable and safe operation of the electrical infrastructure.
Relay Protection. Central ▇▇▇▇▇▇'▇ field personnel and personnel from Con Edison's Protective System Testing and Relay Protection Engineering departments shall coordinate the design, installation, and maintenance of the relay protection for the Second Tie with each other.
Relay Protection. 1. Seller has the following relay protection schemes:
a. Seller has overcurrent and differential relay protection on the transformer bank. For transformer trouble, the bank lockout relay operates, tripping the total bank breaker and the Company's 115 kV circuit breaker. When this lockout relay operation occurs, Seller's personnel will not be able to close the Company's 115 kV circuit breaker.
2. Company has the following relay protection schemes:
a. Non-directional total overcurrent relays that back up the Seller's bank overcurrent relays and trip the Company's 115 kV circuit breaker. b. Directional voltage-sensitive overcurrent relays that trip the Company's 115 kV circuit breaker.
