or to the latest edition of IE 9-4 or other equally reputed national or international standards. The LA shall be station class, heavy duty, non-linear resistanc , type gapless (without any series/ shunt gaps), and herme tically sealed lightning arrestor , outdoor type suitable for installation in open yard /four pole structure. The LA shall be designed to provide maximum protection against lightning and switching surges. The Surge Arrestor shall be suitable for duty cycle of circuit breaker in the system and shall be capable of discha rging over-voltage occurring dur ing switching of unloaded transformers, reactors and long lines. All other Equipment (. Rail Pole, Conductors ,Tubular Bus tu bes Clamps connectors, insulators etc for Switchyard as required shall be considered as per State Utility/ REC standard specification an to establish the Grid Connecti vity. 0.0.0 HT SW ITCHBOARD (INDOOR) 3 kV CICO Switchboard & 6.6 kV Switchboard 1.0 TECHNICAL PARTICULARS ND DESIGN PARAMETERS Sl.
