Description:
The RLHClOO transformer unit used in REGlOO and REGllO contains
five voltage and six current intermediate transformers which convert the
inputs from the VT's and CT's to signal levels suitable for the protection
functions. The eleven output signals are fed to the analogue bus.
Three voltage transformers, with rated input voltage 1 10/寸3 volts, are
used to connect three phase voltages to the bus.
One transformer, with rated input voltage 240 volts, is used to connect the
neutral point voltage to the bus. One transformer, with rated input voltage
110 or 220 volts, connects the injection reference voltage of the rotor earth
fault protection to the bus.
Three transformers are used to connect three phase currents to the bus.
One current transformer, with mu-metal core to minimize phase angle
errors, is used to connect the current in phase R to a bus feeding the
reverse power and loss-of-excitation protection. These current transformers
can have rated primary current 1 or 2 or 5 amps.
One current is used to connect the residual (31。) current to the bus feeding
the stator earth fault protection. The transformer can be chosen with rated
primary current 0,5, 2, 5, 25 or 125 milliamps.
One current transformer, with mu-metal core to minimize phase angle
errors, is used to feed a bus connected to the rotor earth fault protection.
The input is fed from the current injection unit of the protection. Rated
input current is 10 milliamps.
