Function of device 2.1 Three-section composite voltage block direction over-current protection This device sets up three-section over-current protection. Each has three time delays. By setting the control word soft strap, it can be set that whether each of the protection is on or off and whether it is equipped with direction judgment( it can be set as positive or reverse), and whether it is blocked by composite voltage. The angle of maximum sensitivity of directional element is -30°.when positive direction，direction action zone is -50°~110°.when negative direction，direction action zone is 130°~290°.（assume U=0°，the change of the phase of I determines direction action zone. With 90 ° wiring, there into，Ia correspond to Ubc，Ib correspond to Uca，Ic correspond to Uab）. Composite voltage component consists of negative sequence voltage U2(over-voltage) and phase-to-phase low-voltage U（the minimum line voltage）.It is used for block over-current protection when any fault occurs. When either negative sequence voltage U2 or low-voltage U is satisfied, over-current protection can be on, otherwise, over-current protection is blocked. When composite voltage operates, the device will output the signal to other side backup protection through output terminal, in order to control the over-current protection output. That is to say, besides accepting its side composite voltage block, the over-current protection can also accept other sides’ composite voltage block. The protection logic is shown in Figure 2-1. Figure 2-1 Operation logic of composite voltage block direction over-current protection 2.2 Zero sequence voltage alarm function When zero sequence voltage is more than zero sequence voltage setting, the protection will operate after delay. The protection logic is shown in Figure 2-2. 8 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 Figure 2-1 Operation logic of Zero sequence voltage alarm function 2.3 Bus charging protection Bus charging protection is the time limit instantaneous over-current protection. The protection is only on for bus charging for a short time. When the device detects its side breaker changing from trip to close, bus charging protection will be on for a short time. When the operating condition is met, the protection will trip its side breaker after set delay. The on time can be set. When the on time is over, the bus charging protection will be off. The protection logic is shown in Figure 2-3. Figure 2-4 Operation logic of bus charging protection 2.4 Zero sequence current protection A one-step definite time limit zero sequence current protection is provided, which can be set as trip or alarm. When the trip function is switched on, the alarm function is released automatically.When zero sequence current is more than zero sequence over-current setting, the protection will operate after delay. The protection logic is shown in Figure 2-4. Figure 2-4 Operation logic of Zero sequence current protection 2.5 Overload protection A one-step definite time limit overload protection is provided, which can be set as trip or alarm. When the trip function is switched on, the alarm function is released automatically. Three phase A, B, C ，when maximum phase current is more than over-load setting, the protection will operate after delay. Protection operating logic is as shown in Figure 2-5. 9 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 Figure 2-5 Overload operation logic 2.6 Starting fan When a certain phase current is more than starting fan setting, the output relay will block.

ON/OFF I >Iset t/0 Protection output sequence Figure 2-6 Operation logic of Starting fan 2.7 Block voltage regulation When a certain phase current is more than block voltage when a certain phase current is more than block voltage regulation setting, the output relay will block after delay. The protection logic is shown in in Figure 2-7. ON/OFF I >Iset t/0 Protection output sequence Figure 2-7 Operation logic of Block voltage regulation 2.8 PT failure alarm The judgment criterion of PT failure depends on the wiring mode. When the PT failure block function is switched on, if PT failure occurs, the under-voltage protection will block the compound voltage component and current directional component. The judgment criterion of PT failure is as follows:  V-V wiring mode The current value of the phase with the maximum current is less than the maximum load current (using the setting value of the overload current). ① Maximum inter-phase voltage < 30V, and current of any phase > 0.1In. ② Negative sequence voltage > 8V If any of the above conditions is met, the delay (settable) will report PT failure, and will return when failure disappears.  Y-Y wiring mode The current value of the phase with the maximum current is less than the maximum load current (using the setting value of the overload current). ① When |Ua+Ub+Uc|>7V, and the modulus difference between the maximum and minimum line voltages is greater than 18V, it is thought one or 2 phases have PT failure. ② |Ua+Ub+Uc∣> 7V, the minimum line voltage is less than 18V, used for detecting 2-phase failure. 10 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 ③ When MAX{Uab,Ubc,Uca}<7V,and the current of any phase > 0.1In, it is regarded as PT 3-phase failure. If any of the above conditions is met, the delay (settable) will report PT failure, and will return when failure disappears.

When in normal operation，the sum of the three phase current of each side is zero. (less than 0.1 times rated current).When one phase CT failure occurs，the sum of three phase current is not zero (more than 0.1 times rated current). In order to distinguish with ground fault，the following judgment should be conducted: ①Among the three phases，the current of the one with the minimum current is zero. (less than 0.1 times rated current). ②The current of the one with the maximum current is not zero. (more than 0.1 times rated current), but less than CT failure block current. 2.10 Operate circuit break This function can be selected or not. When this function be selected, the device monitoring the HWJ and TWJ states. If HWJ and TWJ both On or Off, the delay (settable) will report operate circuit break, and will return when failure disappears. 2.11 Integral energy The software accumulates active and reactive powers into active and reactive energy in real time. 2.12 Fault recorder 11 PT failure component User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 See the communication coding table for the protection voltage and current waveform data collected by the recording unit. 2.13 Network print Device supports network printing function, can print remote control information, SOE information and the setting parameter list. The printer IP address must been set rightly on the device (the network segment of printer must be as same as that of device IP addresses), then connect a printer, put on "real-time report print ", it can print the current remote control information or SOE information when device is connected to the background (including remote communication shift, protection action), and can print the current SOE information when device is not connected to the background. In addition, when press the "ok" button in the "print report" or "print setting value" menu, it can print the all setting parameter or the all report information, including action value. 2.14 Virtual correspondent node remote test The function is used to complete the communication node remote test of the device, do not need to access the actual analog electric quantity or the input quantity. Specific operation as follows, connect to the background, In the remote test menu, operate the “virtual input test”, the “virtual measure test” and the “virtual SOE test” menu in the “remote test” menu, press the "OK" button after the modification of various settings, then by observing the background pop-up warning window or the change of the corresponding value, to determine whether the device communication node is right. It is convenient for debugger to debug the device on-site. When you are in the mode of remote test, the all protect must be off. 2.15 GPS clock synchronization The GPS clock synchronization signal is input as rs485 differential voltage, the device is able to receive GPS clock second synchronization. If there is GPS signal, there will be flashing on the bottom of cycle menu. Otherwise won’t. The principle of GPS clock synchronization: The second pulse or minute pulse act with the monitoring system, the time base with second precision is sent by monitoring system, when the GPS second differential signal arrives, the time base is unified and the milliseconds are cleared. The device is able to receive GPS clock second synchronization or IRIG-B through RS485 differential voltage, and it can be done with monitoring system to accomplish GPS precise clock synchronization or Ethernet-based SNTP synchronization. 2.16 Overhaul status When the device put into overhaul plate, remote sign, remote measure can uploading background computer. But the device can’t remote control by background computer. The SOE event、Alarm event、Trip event, etc also can’t uploading background computer. 12 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 3.

An anti-trip relay will be selected depending on the current of the trip/closing circuit of the circuit breaker. However, this has poor generality and can hardly be realized for circuit breakers with low trip and closing currents (such as 10KV circuit breakers from AEG Company in Germany, whose trip and closing currents are not greater than 0.2A). To simplify wiring and design finalization, and to improve the generality of the product, we offer a new operating circuit shown below. Spring mechanism operating circuit 35 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 Permanent magnetic breaker operating circuit In the diagram, When the SA is connected to 5,6 contact，The SA is at the “Remote” position, the power of the remote control circuit will be switched on, closing and trip with remote control. when the SA is connected to 9,10 contact, The SA is in manual closing state. when the SA is connected to 1,2 contact, The SA is in manual Tripping state. 36 User’s manual of MTPR-850Hc transformer backup protection and monitoring device WLD[K]-JY-315-2018 Note: The dotted line outlines the internal circuit of the protection device. All our devices marked with “anti-trip circuit” are designed on this operating circuit. Terminals Tn1, Tn2 corresponding to the protection relay Jn are determined by the corresponding protection output control word. Jn can be any one or more of Protection outputs 1-8. Whether local or remote control, the precondition to jump is Terminal A06 of the device is always connected to +KM. After manual or remote controlled closing, if a short-circuit fault occurs, the protection will operate to trip the circuit breaker. Though Terminal A06 of the device is connected to +KM, the closing circuit is disconnected by TBJ1 and will not be closed again. In this way, circuit breaker jump is effectively prevented. 37
