Arc fault protection is a relatively new technique employed for the fast clearance of arcing faults on Busbars & within metal clad switchgear & associated cable boxes. The arc is detected using an optical sensor & the signal input to a protection device which also monitors the load current on the system. Conventional current based protection techniques are at times challenged by the nature of arcing faults, and can result in slow protection clearance times. Slow protection clearance times increase the risk to nearby personnel and increase the degree of damage to plant and equipment. By employing an optical detection technique, Arc Fault Protection results in fast clearance of arcing faults.
When an arc fault start current is coincident with a signal from the optical sensor a trip command is output. An Arc trip only signal can be achieved within 10ms which can be considerably faster than that provided by a traditional IDMT overcurrent relay. This is because the onset of an arcing fault can occur at relatively low fault currents. Arguably the greatest risk of arc fault damage exists at the CB cable termination & in the CB chamber itself due to the slow clearance times of the IDMT feeder protection.
The ReyArc range of protection devices provide multiple arc fault protection schemes depending on your protection system requirements:

7XG3120 Arc Fault Monitor Detects Arc faults independently & in parallel with an overcurrent check relay.

The 7PJ13 Trip Circuit Supervision Relay is an electronic-circuit based relay. The relay is a member of Siemens Reyrolle protection devices product family. It is used to monitor and supervise the integrity of a circuit-breaker’s trip coil and other wiring circuits of low-voltage and medium-voltage networks.
Features
The 7PJ13 is connected with a circuit-breaker to monitor the trip circuit positions (make or break). The 7PJ13 generates a trip circuit failure alarm, either if the trip circuit supply is disconnected or if the trip circuit connection is changed to an open circuit. Trip circuit continuity is measured by supplying the supervision current of 0.7 mA to 1.5 mA and sensing the flow of current with two optocouplers. The circuit-breaker contact indicates the status of the relay whether the circuit-breaker is in a make position or a break position.
The features of the Trip Circuit Supervision Relay are:

Model Name/Number | PMU GP_4 |
Application | monitoring of transient processes in energy supply systems |
Communication protocol | IEEE C37.118 |
Siemens Phasor measurement units (PMUs) from Siemens general protection system and its measured synchrophasors make a valuable contribution to the dynamic monitoring of transient processes in energy supply systems. These data are the basis for the Wide Area Monitoring system SIGUARD PDP. This fast monitoring system detects the events and trends in grids with fluctuating load flows or highly loaded lines which conventional systems cannot detect at all or can detect too late.
SIEMENS PHASOR MEASUREMENT UNITS : FEATURESPhasor measurement units (PMUs) measure current and voltage by amplitude and phase at selected stations of the transmission system. The high-precision time synchronization (via GPS) allows comparing measured values (synchrophasors) from different substations far apart and drawing conclusions as to the system state and dynamic events such as power swing conditions.
All SIPROTEC 5 devices can be used as a phasor measurement unit. When selecting the option “Phasor Measurement Unit”, the devices determine current and voltage phasors, provide them with highly accurate time stamps and transmit them for analysis together with other measured values (frequency, speed of frequency change) using the IEEE C37.118 communication protocol, which are typically sent to the control center.
SIGUARD PDP (Phasor Data Processor) is a system for Wide Area Monitoring and Grid Monitoring that, as its measured variables, uses synchrophasors from phasor measurement units serving as sensors.
Phasor measurement (PMU) with SIPROTEC 5
PMU - overview of function
A phasor measurement unit (PMU) measures the phasor values of current and voltage. These values get a high precision time stamp and together with the values of power frequency, power frequency change rate and optional binary data that are also time stamped are transmitted to a central analysis station. The standardized transmission protocol IEEEC 37.118 is used to do this.
Structure of the function group
The PMU function group is activated by selecting the protocol IEEE C37.118PMU on an Ethernet module (electrical or optical). The PMU obtains the measured values from the measuring points and the precise time from time synchronization. The time-stamped synchrophasors for current and voltage are formed from this and transferred together with additional values via the communication module to a server (PDC, Phasor Data Concentrator).
PMU - function description
The synchrophasors, sent from the PMU in a continuous data stream to a PDC, are provided with time stamps and thus are comparable with the measured values of other PMUs. The power frequency, the power frequency change rate and optional binary information are also transmitted as time-stamped measured values. Therefore, you receive an overview of the transient processes in a distributed energy transfer system, for example network fluctuations and compensating processes.
Synchrophasors of the PMU | Measured values from the measuring points |
Continuous updating (measured value of current) with, for example, 10 values per second (reporting rate) | Slow updating (typically every 5 seconds) |
Every measured value has a time stamp | No time stamp for the measured values |
Phasor values of current and voltage (amplitude and phase angle) | RMS values without phase angle |
