DTM7033 – Machine Differential Protection
Products family : Generator Protection
Sector : Industry
The DTM 7033, three-phases percentage differential relay, protects rotating machines against internal faults.
These faults, generally caused by insulation ageing, require sensitive detection and fast clearing.
The DTM 7033 meets these requirements as a result of :
– A low setting threshold, adjustable from 2 to 14% In.
– A dual slope bias feature, the first level being adjustable from 2 to 20% and the second level being fixed at approximately 50%.
