Shaft Voltage and Current Monitoring System for Turbo Generators Continuous High Speed Acquisition of Shaft Voltage and Current Ethernet and Modbus RTU Interfaces Standalone Operation Local True Color Touch LCD General Description Rotor insulation condition monitoring for turbo generators The Shaft Voltage and Current monitoring system for turbo generators is based on the UDL-8000 data acquisition and monitoring system family for online condition monitoring of high voltage insulation systems and machines. UDL-8000 is a multi - modular system with a central CPU controller, various different signal conditioning modules and sensor interfaces (up to eight modules per controller) and application specific software packages as e.g. the package SUI, used for the acquisition, evaluation and monitoring of the shaft voltage and the shaft current. The shaft voltage is measured by a dedicated pickup on the exciter end. The shaft current can either be measured by a rogowski coil around the shaft or by measuring the shaft current through the grounding brush. The sensors are connected via the Module M8016 to the UDL-8000 monitoring system. The module offers the interface for a reference sensor or reference source, a galvanic insulated input for the shaft voltage signal, 2 shaft current inputs (for Rogowski Coils and for CT’s) and five 4-20mA analogue inputs for the acquisition of the machine operation condition, The UDL-8000 Controller offers standard interfaces as Ethernet, digital in - and outputs, relay contacts and Modbus RTU. The Ethernet Interface is used for the communication with the analysis software running on a windows based computer the real-time data visualisation and analysis. Additionally the UDL-8000 system can be connected to the TMS-2000 Database Server to record continuous the acquired signals (Monitoring).
