2. Function of device
2.1 3 sections of compounded voltage block overcurrent protection
This device has 3 sections of compounded voltage block overcurrent protection. They are
instantaneous over-current protection, the time-limit instantaneous over-current protection,
over-current definite-time limit protection respectively. The current and time setting values of
each section can set separately. When the maximum phase current is greater than the setting
value of the current, and the negative sequence voltage (the negative sequence voltage is
synthesized from the phase voltages) or Under-voltage (being the line voltage; if one or more of
the 3 line voltages is/are less than the Under-voltage setting value, Under-voltage component
operates to open the over-current protection) condition is met, it will operate on trip after a delay.
The protection operation logic is shown in figure 2-1(using instantaneous over-current protection
as an example).
Note: the negative sequence voltage (U2) is compound by each phase voltage, low voltage
is the minimum value of three phase line voltage.

2.2 Inverse time limit over-current protection
As stipulated by the IEC (IEC255-4), the following 4 standard characteristic equations are
usually used. The user may select one as the case may be:
t 0.14 0.02 p
Standard inverse time limit: ( I / I p ) 1 (1)
13.5
Unusual inverse time limit: t ( I / I ) 1
p (2)
p
t 80 2 p
Extreme inverse time limit: ( I / I p ) 1 (3)
120
Long inverse time limit: t (I / I )
1 p (4) p
Where: I is the fault current, Ip is the setting value of the inverse time limit starting current,
τp is the transformer’s overcurrent inverse time limit constant, corresponding to the overload
capacity of the transformer, derived from calculation.
When the amplitude of the inverse time limit overcurrent of any of phases A, B and C is
greater than the setting value of the inverse time limit starting current, the device will operate on
trip according to the inverse time limit characteristic curve. The software makes selection by
inverse time limit characteristic control word. The protection operation logic is shown in Figure
2-2.
Note: Imax=max{Ia,Ib,Ic},the same below

2.3 Negative sequence overcurrent protection
By processing of the currents of Phases A, B and C, the negative sequence current is
calculated. The negative sequence overcurrent protection is available in the definite time limit
and inverse time limit modes.
Negative sequence overcurrent definite time limit:If the negative sequence current exceeds
the setting of negative sequence current, the device will operate on trip.

MTPR-810Hc transformer protection and monitoring device WLD[K]-JY-311-2018
Negative sequence overcurrent inverse time limit:Having four characteristic curves for
choice, the same as the high voltage side inverse time limit overcurrent protection.
To avoid any potential protection false operation arising from the asynchronism of the 3
phases upon closing of the circuit breaker, the set delay shall not be less than 0.2S.
2.4 Overload protection
For Phases A, B and C, when the maximum phase current is greater than the overload
setting value, there will be an operation after a delay. The protection output may elect to operate
on signal or trip. The protection operation logic is shown in Figure 2-3.

Imax>Overload T Protection output

Figure 2-3 Operation logic of overload protection
2.5 High-voltage side ground protection
It includes a section of definite time limit Zero sequence Overvoltage protection and 3
sections of zero sequence overcurrent protection. The zero sequence voltage is from the PT
opening triangle. When the circuit breaker is closed, the zero sequence voltage exceeds the
setting value and the setting delay is reached, the protection will operate. The protection output
may elect to operate on signal or trip. The zero sequence Overvoltage trip is blocked via the
position of the switch.
The zero sequence current uses special zero sequence CT, which can detect the primary
cable zero sequence CT current accurately. When the current exceeds the setting value and the
setting delay is reached, the protection will operate. The protection output may operate on signal
or trip.
For ungrounded systems, when a ground fault occurs in the system, the zero sequence
current of the ground fault point is basically a capacitive current with small amplitude. If a zero
sequence overcurrent relay is used to protect it from ground faults, its selectivity can hardly be
guaranteed. The device uploads the amplitude and direction of the zero sequence current by
communication, and the upper computer performs low current ground wire selection. The
protection operation logic is shown in Figure 2-4.

2.6 Low-voltage side ground protection
The low-voltage zero sequence overcurrent protection is available in the definite time limit and
inverse time limit modes, the same as the negative sequence overcurrent protection.

2.8 Body protection
The device has 5 body protections, such as heavy gas trip, light gas alarm, Over temperature
trip, temperature alarm and pressure relief protection. The operation contact signal operates on trip
or alarm subject to CPU processing, and its operating time is recorded by the software.
2.9 Non-electric quantity protection(Can be selected or not)
The device has the 2-way non-electric quantity protection function, switched on/off by
control word, which are used for trip.
2.10 PT failure alarm
The judgment criterion of PT failure depends on the wiring mode. When the PT failure
block function is enabled, if PT failure occurs, the device will exit from judgment of Undervoltage
protection and compounded voltage block 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
10
MTPR-810Hc transformer protection and monitoring device WLD[K]-JY-311-2018
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, single-phase or 2-phase failure occurs;
② |Ua+Ub+Uc| >7V, the minimum line voltage is less than 18V, used for detecting 2-phase
failure.
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, and the time delay reached, the device reports PT
failure, the alarm will return when failure disappears.

See the communication coding table for the protection voltage and current waveform data
collected by the recording unit.
2.14 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 back-ground (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.
2.15 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.
2.16 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.
2.17 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.

Addendum 3: Operating circuit of MXPR-800Hc series device
Traditional operating circuits are started by current, while a voltage maintaining circuit
realizes electric trip prevention. 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.
Schematic diagram of operating circuit
41
MTPR-810Hc transformer protection and monitoring device WLD[K]-JY-311-2018
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.
42
MTPR-810Hc transformer protection and monitoring device WLD[K]-JY-311-2018
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.
