Airgap Flux Probe for Rotor Interturn Short Circuit Detection of Hydro Generators, Turbo Generators and High Voltage Machines.
The ASC-2520 Magnetic Flux Sensor is one of the ASC family of airgap search coils used to detect faults in the rotor winding insulation of hydro generators, turbo generators and high voltage machines .
The body is made out of peek and the sensing element is encapsulated within high temperature epoxy resin and can be individually designed to suit specific machine construction.
The probe is installed on the stator tooth within the airgap between rotor and stator and the integrated small high temperature cable allows an easy routing outside of the machine. The open wire design allows the cables to be laid through the ventilation holes instead of passing them through the end winding section. The Probe measures the variation of the magnetic flux created from each rotor coil. It withstands up to 2 Tesla and is designed to operate for more than 155°C. The high temperature signal cable can be permanently used for up to 155 °C.
