The rated current of current transformer secondary side is 1A. the internal power supply 24V is selected for switch quantity input (Dry contact input). The tripping coil voltage is 24V. RS485 is not used. The ordering type is CK D4 S1 N 4 FUNCTION CONFIGURATION 4.1 PHASE CURRENT TWO ZONE DEFINITE TIME PROTECTION Two-zone time definite protection includes time definite rapid breaking and time definite overcurrent. The unit checks three phase current. The unit outputs tripping signal after settable time delay when a current is more than the current setting. Two zones of protection shall selects separately on or off. The current setting and time setting may be set separately. The protection operation curve is seen in Fig tec P CK010 Self-Powered V 4.F Page 8.
9 4.2 PHASE CURRENT INVERSE TIME PROTECTION The phase current Inverse time protection provides three curves for selection, i.e., o Normal inverse time, o Very inverse time and o Extremely inverse time. Long time invers is not supported by the CK010 relay. tec P CK010 Self-Powered V 4.F Page 9.
10 4.3 ZERO-SEQUENCE DEFINITE TIME PROTECTION One-zone zero-sequence definite time protection is used to check the ground current for neutral point insulation or compensation system. The capacitive current is more heavy in long cable system. Because the zero-sequence current of indirectly grounded system is less, it required that the unit measures the zero-sequence in higher accuracy, so the ratio of zero sequence current transformer shall be selected more carefully. Zero sequence time definite protection may be selected to throw in or drop out. The current setting and time setting may be set separately. 4.4 ZERO SEQUENCE INVERSE TIME PROTECTION The zero sequence inverse time protection provides three curves for selection, i.e., normal inverse time, very inverse time and extremely inverse time. Time-current equation of three curves and curve characteristic is as the same as phase current inverse time protection. 4.5 EXTERNAL CONTACT TRIP DIRECTLY The unit has two switch inputs circuits. The inputs is internally powered - (Only dry contacts input required from tripping devices). Both of switch inputs are connected directly to the trip output. The trip time delay may be set. It is used normally for Transformer Bucholtz Temp trip Explosion or expansion trip.. Throw-in or drop-out is selected with a keypad. 4.6 HEAVY CURRENT BLOCK TRIP Mainly used for (Load Break Switches) This function is used mainly for load switch + fuse. Because the load switch has not ability to break short-circuit current, the unit shall block all of protection functions (including external contact trip directly) if the load current is more than set block current when this function is started. The fault is cut off by the fuse to assure that the load switch is not damaged. This configuration may meet requirements of short-circuit fault cut off and overload cutoff to make protection function fully perfect. This function must be canceled when a breaker is used. 4.7 PASIVE TRIP OUTPUT CONFIGURATION The unit has output Trip Terminals. Contacts are potential free contacts These contacts are latching and needs to be reset from the HMI buttons. 4.8 Tripping Contacts Terminals 17 and 18 is used to drive tripping. When active pulse output is selected, the unit may supply 24V~220V, 10A (the highest) short time pulse energy, which repeats output in interval of 250ms to ensure the breaker off. tec P CK010 Self-Powered V 4.F Page 10.
