Generator Instrumentation

Coupling capacitors for partial discharge measurement

• Nominal voltage 12/17.5 kVrms
• Embedded quadrupole with reference voltage output
• Embedded overvoltage protection
• Capacity 1000 pF

Optical accelerometers for end-winding measurement

• Resistive against high electromagnetic field
• Great electric isolation (more than 65 kVrms)
• Double output - displacement and acceleration
• Ouput sensitivity: acceleration 100 mV/g

Rotor magnetic flux sensors

• The sensor core is a search coil, detecting passing of every rotor winding coil
• Each sensor is manufactured individually according to generator construction

Coupling capacitors for partial discharge monitoring

• Nominal voltage (between phases) 16 kVrms
• Epoxy-mica
• Usage for hydro and turbogenerators and large industrial motors
