Protection against thermal damage caused by overloads on machines (transformers, motors or generators).
The thermal capacity used is calculated according to a mathematical model which takes into account:
The thermal capacity used calculations may be used to calculate predictive data for process control assistance.
The protection may be inhibited by a logic input when required by process control conditions.
The thermal capacity used is calculated according to a mathematical model which takes into account:
- current RMS values
- ambient temperature
- negative sequence current, a cause of motor rotor temperature rise.
The thermal capacity used calculations may be used to calculate predictive data for process control assistance.
The protection may be inhibited by a logic input when required by process control conditions.
