FOR INTERPOSING RELAY CABINET FUNCTIONS.
INTERPOSING RELAYS SHALL BE USED FOR SUBSTATION CONTROL. INDICATION, AND PROTECTION FUNCTIONS, WHERE
NECESSARY, INTERPOSING RELAYS SHALL BE OF THE LATCHED-IN TYPE ESPECIALLY FOR THOSE CONCERNING THE MODE SELECTION FUNCTIONS. CONTROL SIGNALS TO THE SWITCHYARD SHALL BE CONNECTED TO THE INTERPOSING RELAY CABINET WA INTERPOSING RELAYS MOUNTED INSIDE THE CABINET. ALL INTERPOSING RELAYS SHALL BE USED IN CONJUNCTION WITH ONLY THE DISCREPANCY CONTROL SWITCHES FOR BREAKERS AND MOTOR OPERATED DISCONNECT SWITCHES, SYNCHRONIZING SELECTOR SWITCHES AND RECLOSER CUTOFF SWITCHES WHICH ARE INDICATED ON THE CONTROL AND PROTECTIVE RELAY SWITCHBOARDS.
THE INTERPOSING RELAYS SHALL BE FURNISHED MOUNTED AND WRED WITH SUFFICIENT QUANTITIES TO FULFIL THE REQUIREMENTS OF SUBSTATION CONTROL, INDICATION, AND PROTECTION FUNCTIONS AS SPECIFIED. NOT LESS THAN 10 PER CENT SPARE OF EACH FUNCTION OF INTERPOSING RELAYS SHALL BE FURNISHED AND MOUNTED INSIDE THE CABINET, HOWEVER THE MINIMUM OF TWO SPARE RELAYS SHALL BE FURNISHED AND MOUNTED FOR EACH TYPE OF RELAYS. THE COILS OF THE RELAYS SHALL BE SUITABLE FOR CONTINUOUS DUTY AT THEIR NORMAL OPERATING VOLTAGE.THE COIL RATING SHALL BE 125 VO-CALL CONTACTS SHALL BE OF THE RENEWABLE TYPE WITH AMPLE CURRENT-CARRYING AND INTERRUPTING CAPACITY FOR THE APPLICATION, AND SHALL WITHSTAND AT LEAST 10A AT ONE SECOND,SA AT CONTINUOUS DUTY, AND BE CAPABLE OF INTERRUPTING 0.3A OF INDUCTIVE CURRENT(L/R « 40 MS) IN A 125V D-C CONTROL CIRCUIT.
