Common use of Protection System Clause in Contracts

Protection System. Protection System shall be designed to reliably detect faults on various abnormal conditions and provide an appropriate means and location to isolate the equipment or system automatically. The protection system must be able to detect power system faults within the zone. The protection system should be able to detect abnormal conditions such as equipment failures or open phase conditions. Every Element of the Power system shall be protected by a standard protection system having the required reliability, selectivity, speed, discrimination and sensitivity. Where failure of a protective relay in the M/s. ________(Transmission Licensee)_ system has substantial impact on the grid, it shall connect an additional protection as back up protection besides the Main protection. Notwithstanding the protection systems provided in the grid, the M/s. ______ __(Transmission Licensee) shall provide requisite protections for safeguarding their system from faults originating in the grid. Bus bar Protection and Breaker Fail protection or Local Breaker Back-up Protection shall be provided wherever stipulated in the Regulations. Special Protection Scheme such as Under Frequency relay for Load shedding, voltage instability, angular instability, generation backing down or Islanding Schemes may also be required to be provided to avert system disturbances. Protection co-ordination/Relay co-ordination shall be done at State level in coordination with the STU and with WRLDC/WRPC. The M/s. ______ ____(Transmission Licensee) shall develop protection manuals conforming to various standards for the reference and use of its personnel. All 220 kV and above stations shall have bus bar protection scheme, over flux, under voltage, over voltage relays and any other protection recommended by Regional PSCC of WRPC/STU. Users shall provide information to SLDC regarding installation and healthiness of protective equipment like df/dt relays etc., reactive compensation on UFR monthly basis.

Protection co-ordinationordination issues shall be finalized at regional levels by Regional Electricity Board/ Regional Power Committee and for Intra-State lines by STU The MSETCL shall develop protection manuals conforming to various standards for the reference and use of its personnel. Protection Systems shall be provided by all Transmission Licensees and Users to isolate the faulty equipment and protect the other components against all types of faults, internal/external to them, within specified fault clearance time with the reliability, selectivity and sensitivity: Provided that all Users or Transmission Licensees shall provide protection systems as specified by the Authority and the provisions of the protection code and Connection Agreement. Relay co-ordination setting coordination shall be done at State level in coordination with the STU and with WRLDC/WRPC.
