SynchroGuard is an innovative monitoring and automation solution for smart grids. Thanks to unique measurement devices and advanced data-processing algorithms, it provides to utility operators a real-time view of the grid status, enables safe integration of renewable energies and electric vehicles by efficiently managing power flows, and improves grid reliability by accurately locating electrical faults. The goal is to support electrical utilities in the power grid modernisation and digitisation that is mainly driven by increasing power generation from renewables energies and electric vehicles as well as stringent regulatory requirements.

Implementation Stories

SynchroGuard by Zaphiro Technologies
Implemented by Services Industriels Lausanne (SiL) in Lausanne (Switzerland) in 2022

The Services Industriels de Lausanne (SIL), conducted a pilot project starting in April 2022 with the aim to install Zaphiro’s SynchroSense and SynchroGuard Solution on four Medium Voltage (MV) feeders to monitor real-time events, locate faults, and increase situational awareness. Goal is to improve and accelerate the fault localization process and improve the SAIDI/ SAIFI indicators.


Expected to decrease fault intervention time, to reduce costs by improving existing asset utilization, and to allow a larger share of renewables to connections


The environmental benefits

  • 2x fewer sensors required to reach the same level of state estimation accuracy
  • High quality and high speed measurement, up to one measurement every 20ms
  • Each MW of PV generation added to 10% of the Italian medium-voltage feeders, can save about 1’000’000 tonCO2/year
  • Up to 300% increase in renewable integration thanks to intelligent network management

The Financial benefits

  • The fault management function allows savings of 1.7M€/year for a city of 400'000 inhabitants, with payback time of about 6 years
  • The solution can save up to 80% of sensor deployment cost for distribution grid monitoring
