Section 4
Differential protection
GUID-3B9FE9F0-8E0F-468C-8094-A6D59B15A64B v1
Motor differential protection is an unit protection as the main protection against short-circuit faults within
the motor.
PSM640 Motor differential protection included five main sub-functions:
• Instantaneous differential protection function
• Ratio restraint differential protection function
• Second harmonics restraint element
• Magnetic balance differential protection
• Automatic doubling of setting value.
In the event of a motor failure, motor differential protection can provide fast and selective tripping for the
faulty equipment.
4.1
Instantaneous differential protection HiSetPDIF
GUID-C19075EB-2EF6-4E09-A498-1C708621021B v1
PSM640 provides instantaneous differential protection. The function feature is low transient overreach
and short operation time, to allow use as the severe motor internal short-circuit fault protection.
4.2
Motor differential protection MPDIF
GUID-A65DBCA5-9F25-46F4-BB02-02C4E8A6B8A8 v1
In the event of a motor failure, MPDIF can provide fast and selective protection against internal faults,
thereby safeguarding the motor.

Three-phase overcurrent protection, three-stage PHPTOC
GUID-D8333935-8BC0-4284-89F6-4D00826D271B v1
PHPTOC is non-directional overcurrent protection function consists of 3 stages. Each stage can be set
enabled or disabled independently. The operation time characteristics of PHPTOC stages 1 and 2 are
based on DT (Definite Time), while the characteristics of PHPTOC stage 3 are based on IDMT (Inverse
Definite Minimum Time). The three stages PHPTOC can meet most application requirements of motor
backup overcurrent protection.
5.2
Earth fault overcurrent protection, two-stage EFPTOC
GUID-59FEDF03-6B10-4E49-90B7-FE3E38993F11 v1
PSM640 provides two stages zero-sequence current protection, detecting the zero-sequence current of
the motor stator earth-fault. Each stage can be enabled or disabled separately and independently. The
two stages EFPTOC can meet most application requirements of motor earth-fault protection.
5.3
Overload protection OLPTOC
GUID-F7C61A7B-0AB1-4976-BB24-3E7594B715F4 v1
PSM640 integrates overload protection OLPTOC. When the load of the motor approaches or exceeds
its rated capacity, the overload protection detects this condition and alerts the operators. This alert helps
operators to take timely actions to prevent further faults and damage caused by overload.
5.4
Thermal overload protection MPTTR
GUID-CA1A5E37-CEA2-4F39-A57F-1F435A8891C2 v1
In case of abnormal operation of the motor, thermal overload protection can limit the heating state of
the motor to a predetermined range, which can avoid premature aging of the motor insulation. Thermal
overload protection MPTTR evaluated the motor heating during motor operations. The thermal overload
protection will disconnect the power of motor when the calculated temperature exceeds the setting
level . This prevents motor overheating, reducing the risk of motor damage or failure.
5.5
Fuse-Contactor block FCPTOC
GUID-5E43965F-0601-4899-998B-708E6773A275 v1
When the motor is controlled by a fuse-contactor (F-C), any internal faults in the motor should be
interrupted by the fuse. The F-C blocking function monitors the phase current, and when the fault current
exceeds the setting current value, the IED blocks other motor protections to output tripping command to
the contactor. By preventing the contactor from breaking excessive fault current, the safe operation of
the equipment is ensured.
5.6
Motor load jam protection JAMPTOC
GUID-33862A07-0997-432D-A34C-CF06DEE7669F v1
Motor load jam protection JAMPTOC is mainly used to protect the motor from excessive temperature.
JAMPTOC ensures the longevity and reliability of motors by preventing excessive heat.

Negative sequence overcurrent protection NSPTOC
GUID-227EC8C1-694E-464B-B28A-51A2BD32E5D0 v1
In the operation of three-phase motors, the unbalance of three phases are caused by power supply
voltage unbalance and single-phase faults. The negative sequence current will be generated under
unbalanced voltage conditions, it can result motor heating, and damage the motor, so it is necessary to
provide the protection against the negative sequence current of the motor.

The undervoltage function can be applied on components of the power system, such as generators,
transformers, motors and power lines to detect whether the system operates atr undervoltage
conditions. The undervoltage condition is caused by abnormal system operation or power system
faults. The undervoltage protection can be applied independently or can be combined with overcurrent
protection.

resistance grounded, or impedance grounded. In these systems, a ground fault can increase the system
zero- sequence voltage. ROVPTOV typically serves as backup protection or output alarm signal for
system ground faults. Additionally, it can be applied for ground fault protection in generators and motors,
as well as unbalance protection in capacitor banks.

Underfrequency protection FRPTUF
GUID-B0510609-C185-4971-AAAB-C856689DFAFC v1
Maintaining system frequency stability is one of the main principles for the safe operation of distribution
networks and transmission systems. In order to the safe operation of all devices sensitive to frequency in
the network, the system prohibits frequency deviation from the safe operation range.
Underfrequency protection can be applied where high reliability detection of underfrequency in power
systems is required. The low fundamental frequency of the power system indicates a local shortage of
active power, which cannot meet the demand of the load connected to the power grid. Therefore, the
underfrequency protection is applied to disconnect some unimportant load, ensure the balance of active
power and restore the system frequency to the allowable level.

All connections are made on the rear of the case.
1. Connect each signal connector terminal with one 0.5~2.5 mm2 wire.
2. Connect CT/VT connector terminal with one 1.5~4.0 mm2 wire.
3. Connect terminals on the communication module for IRIG-B with one 0.2~1.5 mm2 wire.
The terminal block used for electrical connections is the screw-compression type terminal.
1. Open the screw terminal before inserting a wire into it for the first time. To open the screw terminal,
turn the fixed screw counterclockwise until the terminal hole is fully open.
2. Insert the wire and turn the fixed screw clockwise until the wire is firmly fixed.

IP
1.
Internet protocol. The network layer of TCP/IP protocol packets is widely used in
Ethernet. IP is a connectionless and efficient packet switching protocol. It provides
packet routing, fragmentation and reassembly through the data link layer.
2.
Ingression protection according to IEC standard.
IP20 Ingression protection level is 20, according to IEC standard
IP40 Ingression protection level is 40, according to IEC standard
IP54 Ingression protection level is 54, according to IEC standard

SNTP
Simple network time protocol. It is used to synchronize computer clocks on local area
networks. This can reduce the hardware clock accuracy requirements of each embedded
system in the network. Each embedded node can synchronize with a remote clock,
providing the required accuracy.
TCP
Transmission control protocol. The most common transparent layer protocol used in
Ethernet and the Internet.
TCP/IP
Transmission control protocol over Internet Protocol. In Fact, part of the standard
Ethernet protocol that is included in 4.2BSD Unix. TCP/IP is developed by DARPA for
Internet operation and it encompasses both network layer and transport layer protocols.
While TCP and IP specify two protocols at specific protocol layers, and TCP/IP is
commonly used to refer to the entire US Department of Defense protocol packages
based upon these two protocols, including Telnet, FTP, UDP and RDP, TPZ, TPY, TPX,
TPS using the current transformer class in IEC standard.
UTC
Universal Time Coordinated A coordinated time scale, maintained by the Bureau
International des Poised Mesures (BIPM), forms the basis for the coordinated
dissemination of the standard frequency and timesignals. UTC is derived from the

International Atomic Time (TAI) by adding an integer value of "leap seconds" and it is
used to synchronize with Universal Time 1 (UT1). Thus considering the eccentricity of the
Earth's orbit, the rotational axis tilt (23.5 degrees), but still showing the Earth's irregular
rotation, on which UTC is based. The Coordinated Universal Time is represented by a
24-hour clock and uses the Gregorian calendar. It is used for aviation and navigation, and
sometimes referred to as the military name, "Zulu time". "Zulu" in the phonetic alphabet
stands for "Z", which means "0" in longitude.
