Protection Relays for DSOs
Reliable overcurrent, earth fault and directional protection for MV distribution networks.
The Challenge
Distribution system operators face increasing pressure to minimize outage duration and protect aging infrastructure. Selecting the correct protection relay — with the right ANSI functions, communication protocols, and compatibility with existing CT/VT installations — requires deep technical knowledge. A wrong selection leads to miscoordination, unnecessary trips, or undetected faults.
Our Approach
We analyse your network topology and protection philosophy before recommending any product.
We identify the required ANSI protection functions (50, 51, 67, 79, 87 and others) based on your application.
We verify compatibility with your existing CT/VT measurements and SCADA communication requirements.
We provide product options from leading manufacturers such as Schneider Electric, ABB and Orion EE — with neutral, unbiased comparison.
We support your engineering team through specification, selection and commissioning documentation.
