Generator for coal-fired power plant

  A turbine-driven electrical generator contains a stationary stator and spinning rotor. In operation, it generates up to 21,000 amperes at 24,000 volts of three-phase alternating current (approximately 500 MW). The rotor spins in a sealed chamber cooled with hydrogen gas. The system requires special handling during startup, with air in the chamber first displaced by carbon dioxide before filling with hydrogen. This ensures that a highly explosive hydrogen-oxygen environment is not created. In this application, monitoring the speed of the rotor using a two-wire NAMUR sensor is very important to avoid over-speed. A solution for rotor over-speed protection is to use the PR 5715 programmable LED indicator adding local readout and 2 relays for over-speed alarms and sensor error detection. The 4…20 mA output signal from the PR 5715 is connected directly to the control PLC.Application:PR 5715 programmable LED indicator
Range of 5700 series Multi-functional Panel Meters are characterized by their flexibility and stability. The panel meters meet nearly every demand for display readout of process signals, and have universal input and supply capabilities.
They provide a real-time measurement of your process value no matter the industry, and are engineered to provide a user-friendly, reliable relay of information, even in demanding environment.
Application: Display for digital readout of current / voltage / resistance / temperature or potentio meter signals. Process control with 2 potential-free relays and / or analog output. For local readout in extremely wet atmospheres with a specially designed splash-proof cover.
