three types are controlled by the special network distribution program preset in the unit over current load when a line is overloaded but not severe enough to influence safe operation of the line, ftu f80 will sense that the current excesses the preset “over current start up” value and send out an over current remote signaling alarm transient fault when transient fault occurs, f80 detects and judges according to the preset program that the circuit breaker (c b) in the substation trips, and after the circuit breaker has successfully reclosed once or several times, the system will clear the fault and resume power supply the ftu f80 sends out two kinds of alarm signal over current remote signaling and c b action signaling alarm permanent fault when permanent fault occurs, 80 detects and judges according to the preset program that the circuit breaker in the substation trips, and in case of the circuit breaker failed to reclose once or several times , the circuit breaker will be locked in its tripping mode and the fault cleared off at this time ftu f80 sends out three kinds of alarm signals over current remote signaling, breaker action and breaker locking the following are the protection function build into the ftu • overcurrent (ansi 50/51, 50g/51g) • sensitive earth fault (ansi 50sef) • directional relay (ansi 67) • broken conductor (ansi 46bc) • negative sequence voltage (ansi 47) the ftu is able to report fault event, fault direction and fault clearance event details as time stamped sequence of events (soes) it is also able to save 128 fault events along with

time for delay consider the actual voltage in case of actual value not same with voltage level, rtu have to count time during the actual voltage difference with voltage level if the voltage has been difference until equal with time setting then rtu will send raise/lower command to adjust the tap position of regulator contractor have to designed for rtu able to change value to time delay in unit of second between 10 180 sec and rtu shall able to mem orize last count of time delay (incase rtu lost of dc supply) iii) bandwidth = width of changing voltage level (in unit of %) that rtu will not send the control command to raise/lower tap position of regulator, ie bandwidth = 1% of voltage level at 110vac then the bandwidth will be between 108 9 vac to 111 1 vac contractor shall designed the

the actual number will be displayed when the number of soe items is over 1000, the new soe items will overwrite original ones when the dialogue box is closed then opened again, all the item records will be cleared, and the system is ready to receive new soe items the displayed content includes node number that sends remote signaling deflection, channel number in the node, deflection feature of the remote signaling and remote signaling deflection transmission time 5 7 history soe this interface shows the queue of the latest 512 soe items when the number of soe items is less than 512, the actual number will be displayed when new soe items are generated after the interface has been opened, new records will not be added new soe items will be displayed only after the interface is closed and then re opened 5 8 fault this dialogue box shows whether a certain feeder of a certain node works normally if operation of the feeder is normal, then no remote signaling report will appear in the fault status column, and the received value and processing value in the fault data list column will be zero if fault occurs in that feeder, the system will display fault termination time in the termination item of the fault report, and display causes of fault (phase over current, zero sequence over current, or zero sequence over voltage) and the circuitry status caused by the fault (circuit breaker action, breaker locks and grounding fault) in the fault status information column in addition, the real time phase current and voltage values of one cycle before and after the fault of that feeder will be displayed in the information column of fault data list as shown in the picture, the over current start up value of phase current is set at 6 a and overcurrent occurs in phase a, then the fault information generated under the condition of cb tripping is simulated 5 9 fault current events this interface shows the queue of the latest 36 fault current items when the number of fault
