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:

 

ReyArc Arc Protection range:


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

  • 7XG3123 ARC Fault Module - Designed to connect one or two optical arc fault sensors to a protection relay status input.

  • 7XG3124 IEC61850 Arc Fault Monitor – Arc Fault detection using IEC-61850

SIEMENS REYROLLE 7PJ13 TRIP CIRCUIT SUPERVISION 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:

  • A universal auxiliary voltage range with very low burden (i.e.)
    – AC 24 V to AC 240 V/DC 24 V to DC 240 V
    – AC 110 V to AC 240 V/DC 110 V 20 DC 240 V
    at less than 4 W.
  • A universal supervision voltage range (i.e.) DC 24 V to DC 240 V.
  • A compact design 96 mm x 48 mm (Width x Height)
  • Fitted with flush-mounting
  • Continuous supervision of trip circuit in pre-closed, post-closed condition, and latched trip condition.
  • Detects faults such as auxiliary voltage loss and circuit breakage in supervised circuits.
  • Indicates operational status by a single LED with dual color.
  • The relay complies with IEC 60255 standards.

The 7PG23 electro-mechanical single phase circulating current protection is used to detect earth faults in ‘high impedance’ protection schemes. The relay is typically applied used in transformer protection schemes.

One relay per phase can be applied to detect both phase and earth faults e.g. on reactors and stator windings of large machines.

The relay is a voltage operating device and has a user selectable operate voltage setting. The relay can be used in conjunction with an external shunt setting resistor where a higher operate current is required. An integral non-linear resistor limits over-voltages occurring during system faults. Operation flag indicator. Relays are housed in size E3 cases.

Siemens Reyrolle 7SR157 Numerical Relays Prices: 
The Reyrolle 7SR157 Argus is a combined check and system synchronising relay designed to carry out controlled closing of a circuit breaker using measurements of the line and bus voltages. The relay will prevent closure of the circuit breaker if the differences in phase angle, slip frequency or magnitude of the voltages fall outside prescribed Limits.

 

If the parameters are within limits, the relay will issue an output which can be used to close the circuit breaker directly or in conjunction with an auto-reclose scheme.

 

Housed in a 4U high, size E4 case, the relay provides instrumentation and fault data with integrated input and output logic, data logging and fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS 485 port for remote Connection.
