Fortified Sentinel: The CIT Solution for Uncompromising Reliability & Safety in Substations

Core Problem AddressedTraditional ITs represent critical single points of failure. Core malfunctions due to overload, thermal stress, or internal faults lead to inaccurate metering/protection signals or complete loss of data. Transient surges specifically challenge CITs due to combined voltage/current proximity. These vulnerabilities compromise grid stability and personnel safety.The Fortified CIT SolutionThis solution transcends basic combination by embedding layers of reliability and safety en

A Direct Replacement Solution for Legacy AIS Modernization

Executive Summary: Facing aging conventional Current Transformers (CTs) and Voltage Transformers (VTs) in Air-Insulated Substations (AIS)? Modernization can't mean rebuilding the substation. The CIT (Combined Instrument Transformer) is engineered specifically as a robust, drop-in replacement for your legacy units. Preserving existing foundations and busbar connections, it delivers essential analog compatibility today while seamlessly enabling your phased digital future. Prioritizing ruggedn
