7PG21 Solkor Relay, Siemens Solkor Protection Relay, Siemens Protection Relay

The 7PG21 is a three phase unit differential protection used to detect in zone phase and earth faults. The relay is applied to overhead line and underground cable circuits as well as shorter circuits such as interconnectors.

 

Relays (and associated CTs) are installed at each end of the protected circuit and connected together with dedicated metallic pilot wires.

 

This established protection system provides a simple, robust protection of proven performance facilitating straightforward installation, commissioning and maintenance.

 

Relays have 3 current inputs and are housed in E6 cases.

 

Additional relays and components can be added to the basic protection to provide:

  • Increased insulation level
  • Pilot Wire Supervision to monitor the integrity of the pilot circuit.

Protection Functions:

  • Current differential protection over a single pair of pilot wires

 

Supervision Functions:

  • Optional pilot wire supervision
  • Optional overcurrent guard (check)

Control Functions:

  • Optional unstabilising / intertripping

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.

 

Protection Functions:

  • High impedance restricted earth fault

Features:

  • User selectable voltage setting
  • Integral voltage limiting device

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.

Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue inputs and binary input/output circuits. The optional auto-reclose feature offers an integrated solution for use on OHL feeders.

The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protections.

Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection and rear electrical RS485 port for remote connection are provided as standard, additional ports are available as options.

Our differential protection relay, Reyrolle7SR18, is a numeric three phase differential protection relay used to detect in zone phase and earth faults. This differential protection relay is applied to overhead line and underground cable circuits as well as shorter circuits such as interconnectors.

 

Reyrolle 7SR18 differential protection relays have integral back-up overcurrent/earth fault protection and intertripping channels.

 

Protection Relays (and associated CTs) are installed at each end of the protected circuit. The relays are connected together with a fully supervised fibre optic protection communications link.

 

Relays have four current inputs and are housed in E6 cases. Integrated logic is provided to allow the optimal configuration of relay protection functionality with the relay''s analogue inputs and binary input/output circuits.

 

Protection and instrumentation functionality is accessible via the data comms channel - a front USB, RS485 and IEC 61850 (optional) rear ports.

The 7SR23 DAD is a numeric high impedance circulating current relay has four current inputs, it is used as a unit protection to detect phase and earth faults.

 

The relay can be applied to bus bars, connections, transformers, reactors and motors.

 

The relay is used in ‘high impedance’ applications in conjunction with external stabilising resistors and non-linear resistors (Metrosils). Standardised external components can be provided in an Epsilon case to facilitate design and installation.

 

The integral CT supervision feature detects open circuits in the CT secondary wiring circuits, a consideration where CT circuits are switched.

 

Relays are housed in E6 or E8 cases. Integrated logic is provided to allow the optimal configuration of relay input and output functionality. Protection, instrumentation and metering functionality is accessible via data comms channels. A front fascia USB port for local connection and RS 485 rear port for remote connection are provided as standard, additional rear ports are available as options..
