Dedicated protection relays are used for monitoring each section of the power system (generators, transformers and transmission lines), to recognize a damaged system component for a specific fault event (under/over voltage, under/over frequency, over-current, earth-fault, reverse power, etc.), and to disconnect it quickly and reliably, protecting humans and the other healthy parts of the system while maintaining the power distribution.
Adding optional modules to the GTU 103.2-S configuration, the available list of experiments and system capabilities are expanded.
DL GTU103A-S: Generation protection
DL GTU103B-S: HV line protection
DL 2108T22: Distance protection
DL GTU103C-S: Transformer protection
