Synaptec reduces outage and operational costs with the world’s only distributed sensor technology for operators of complex power systems.

Synaptec’s passive sensors are ideal for faulted section identification in mixed or hybrid circuits containing both overhead lines (OHL) and remote cable sections, cable tail ends, or OHL and transformers. Synaptec enables discrete auto-reclose over longer distances, distinguishing overhead from underground faults in millisecond timescales.

Synaptec’s Mixed Circuit Protection (MCP) system installs easily to deliver reliable and secure faulted section identification in more locations over longer distances than conventional and optical current transducers. For more information, you can read our paper here.

Underground / overhead line challenges: Why are MCP solutions needed?

  • Undergrounding any or mulitple parts of a circuit makes protection more challenging
  • Protection should distinguish overhead and underground faults, to enable auto-reclose on transient events, and to block auto-reclose commands if the faulted section is underground
  • Conventional and optical instrumentation both lack the range and the ability to instrument multiple remote locations, without significant infrastructure complexity and cost
  • Synaptec’s technology enables multi-zone differential line protection along any feeder without traditional infrastructure or challenges with reliability, security, or maintenance
  • Travelling wave-based solutions are not suitable systems with short cable sections (<1 km)

Discretely monitor differential currents on up to 5 cable sections from one system.

Key benefits

  • Robust and familiar equipment – The PSC is compatible with industry-standard CTs
  • Safe and simple to install – No fibre wraps, multiplexers or special installation skills required
  • No remote infrastructure – No need for civil works to house clocks, control power or data networks
  • Reliable – 5P accuracy over -40°C to +80°C with active temperature compensation
  • Robust – Immune to fibre disturbance, power outages, electromagnetic interference, or ambient temperature

On-board protection algorithms

Provides both ANSI 50G earth overcurrent and 87L differential current protection logic, depending on operator requirements, to instantly identify faults on the network and inform protection response. Multiple MCP zones can be defined to cater for any circuit configuration.

Digital ready

Compatible with conventional relays and streams both Sampled Values and GOOSE messages for IEC 61850 / IEC 61869 systems.
