With a large number of different tripping characteristics and adjustment possibilities, the tripping characteristic can be made suitable for almost every type of generator with regard to its special thermal time-constant.
There is a choice between an independent or an inverse time tripping characteristic. In case of low unbalanced load, a warning is given after an adjustable time delay. In case of inadmissible high unbalanced load, the MRS1 relay trips in accordance with the set characteristic.
Features
• Digital filtering of the measured values by using discrete Fourier analysis to suppress the high frequency harmonics and DC components caused by faults or system operations
• Selectable protective functions between: definite time over current protection and inverse time over current protection
• Consideration of the thermal constant of the generator
• Storage of trip values
