SASensor ®

SASensor® is a digital substation automation system comprised of a high-performance central computing unit (CCU) capable of providing protection, control, monitoring, communication and assets management function by collecting the data those functions require. SASensor® uses accurate, highspeed, time synchronised measurements within your substation.

Basic functions

  • Control
  • Monitoring
  • Measurements
  • Disturbance recording
  • Time synchronization


Fail-safe operation

  • Automation
  • Protection
  • Power quality monitoring
  • Redundant configuration
  • Fault location determination


Advanced functions

  • Single point of access
  • Cyber secured access (VPN)
  • Interference free fiber optic cables
  • Integrated single Human Machine Interface (HMI)
  • Robust design for longevity

With only 5 hardware component types, SASensor® does not only great simplify substation engineering it also drives optimization of total cost of ownership (TCO).

SASensor® benefits:

  • 35% less identification, specification, configuration and testing effort
  • Single access point improves cyber security
  • Limited maintenance maximizes availabillity
  • Lower number of stock keeping units
  • Cost savings due to less devices and up to 80% less copper wiring
  • Future proof with all functionality in software
  • Scalable to optimize SASensor® to your application
  • Reduction of Customer Minutes Lost (CML) by 30% due to precise fault location determination

National Grid, the UK electricity and gas transmission company, has been using Locamation’s SASensor® system for more than 25 years. Now it has decided to upgrade to the latest SASensor® CPC control equipment, adopting the new HSR communication protocol and migrating the system onto the latest software release. National Grid is therefore benefiting from a fully updated, software defined centralized substation control, measurement and automation system - all with the shortest possible outage times and keeping the original engineering like in place.

Alliander Heinsberg Netz GmbH is the municipal distribution grid operator in Heinsberg. The company has chosen Locamation’s SASensor® CPC as part of a major initiative to modernize and refurbish its traditional protections relays, with a competitive and future proof solution, which will enable it to cope with the rapidly changing way the grid is used. This is being triggered by the “Energiewende” centralization of generation, increased volatility of supply and demand, the increased dynamics of protection settings and new protections in the future. Alliander also plans to use the data for preventive asset maintenance, thus avoiding unplanned outages. The company has chosen SASensor® CPC as the most advanced Centralized Protection and Control system available, to remotely automate the operation of its substations.
