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
