Description

"The PRS-778 is a numerical distributed transformer protection intended for protecting and
monitoring various transformers of various voltage level, ranging from 1000kV to 110kV. PRS-778 can detect and clear all types of internal faults.
PRS-778 provides fast and selective protection, monitoring and control for two and three-winding transformers, auto transformers, step-up transformers and generator-transformer block units, phase shifting transformers, special railway transformers, shunt reactors, etc. The relay can operate correctly over a wide frequency range in order to accommodate power system frequency variations during disturbances and generator start-up and shut-down."
