CoDiS - RM Permanent Rotor Monitoring
CoDiS RM, Rotor monitoring unit, is wireless diagnostic monitoring of quantities measured directly on the rotor of hydro generator. This is unique solution for monitoring of rotor quantities using wireless technology to autonomously acquire and analyze data in rotation. CoDiS RM is used to monitor Temperature of rotor pole windings, excitation current and voltage, magnetic field and even air gap (used to obtain the real stator geometry by using only one sensor). System continuously records data of all signals measured on rotary part of power generator and through wireless communication is sending the data to server for permanent database storage. CoDiS RM is used to obtain rotor thermal map measured directly on rotor pole windings.
