SPAD346C

Description

trait
Integrated protection: Integrated three-phase differential relay, overcurrent relay and ground fault relay.
Various protection principles: Provide ground fault protection for the high voltage side and low voltage side windings of the transformer according to the required principles, such as the principle of stable differential current and the principle of high impedance.
Accurate correction: high voltage side and low voltage side digital vector group matching, CT variable ratio correction range is wide, through the digital setting to achieve accurate correction.
Sensitive display: Sensitive phase current and phase Angle display facilitates inspection of measurement circuits.
Multiple outputs and inputs: four tripping and four signal relay outputs, five programmable external control inputs.
Strong anti-interference ability: integrated interference recorder, can record current and digital signals, strong anti-electrical and electromagnetic interference ability.
Flexible configuration: The high voltage side and low voltage side can use the same or different current ratings.
