• Binary inputs ESI 48-4 EB2 compliant – avoids spurious pickup from induction on field wiring
• High density I/Os in various combinations depending on case size option
• Ungrouped binary inputs for trip circuit supervision
• Field upgradeable, avoiding costly hardware changes

  • Up to 3 x RJ45/fiber optic ports for single and redundant Ethernet plus additional engineering access
  • From 11 to 30 binary inputs, and 9 to 25 relay outputs, depending on the order code

Simulation & Testing

To aid commissioning, a simulation feature is provided to test the relay’s functionality and response to programmed conditions, without the need for external AC voltage and current inputs. When placed in simulation mode, the relay suspends reading actual AC inputs, generates samples to represent the programmed phasors, and loads these samples into the memory to be processed by the relay. Normal (pre-fault), fault, and post-fault conditions can be simulated to exercise a variety of relay features. Other test operations, such as an LED lamp testing for each color, contact input states, and testing of output relays, are also possible.

The Multilin 850 is an advanced feeder protection relay that provides high performance protection, high density I/O, extensive programmable logic and flexible configuration capabilities. With protection and control logic, the 850 allows for simplified coordination with upstream and downstream disconnect devices. The Multilin 850 supports both industrial and distribution utility feeders. Dual feeders (850D) and multi feeder (850P) in electrical applications are also supported.

Protection & Control

The F35 feeder protection system provides feeder protection, control, monitoring and metering in an integrated, economical, and compact package. As part of the Universal Relay (UR) Family, the F35 provides cost-effective solutions and features high performance protection, expandable I/O options, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The F35 can be configured to protect up to six feeders or protect up to five feeders when bus voltage measurement is required. It also provides fast and deterministic execution of programmable logic necessary for substation automation applications. Graphical programming tools (Viewpoint Engineer), supported by a library of logic components, make the F35 simple to use and configure.

A sensitive wattmetric zero-sequence directional function can be used on isolated or resonant (Petersen coil) grounded, low-resistance grounded and solidly grounded systems to detect ground faults. This function determines the presence and direction of ground faults by measuring the value and direction of zero-sequence power. This flexible element responds to power derived from zero-sequence voltage and current in a direction specified by the element characteristic angle. Power can be selected as active, reactive, or apparent. Therefore, the element may be used to sense either forward or reverse ground.

The F35 has a wide range of protection elements that have many years of proven field experience.

Transmission and distribution systems are essential for the safe, sure routing of power from generation sources to consumers. However, exposed overhead lines transporting power are by nature sometimes vulnerable and prone to fault. In the case of a faulty circuit, the MiCOM range provides speedy protection to trip and isolate it, thereby preventing further damage. Each relay model contains a complete suite of backup protection elements covering all current, voltage and frequency applications. This permits simplified application and spares holdings, because the relay can be adopted as the standard protection platform. 
The MiCOM P84 is suitable for feeders controlled by a single circuit breaker and for complex installations where feeders are controlled by two circuit breakers such as ring bus/mesh corner formations and the breaker-and-a-half configurations.

• Multi-shot 1/3pole & 3pole autoreclosure with check synchronism - adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults.  Improves system stability whilst reducing OPEX.
• Fast CB failure resetting (<3/4 cycle).
• Same heritage as the class leading MiCOMho P44 and MiCOM P54 family of products.

Main characteristics:

• Comprehensive communication options including IEC 61850 Edition 2
• IEC 61850 redundant Ethernet protocols - RSTP, PRP or HSR
• IEC 61850 9-2LE redundant PRP Process bus protocol
