All the instrumentation and control systems used in the power station should be accurately connected to the ground. "Ground" is a common reference point site, which is defined by different names when applied in different situations. In the design of TSI cabinets, there are protective ground and signal ground to avoid noise interference. A correct grounding system can effectively suppress external ...
A steam turbine is both a thermal power device and a high-speed rotating machine. Therefore, in addition to monitoring conventional thermal parameters (temperature, pressure, and vacuum), mechanical parameters must also be monitored to understand the turbine's mechanical operating conditions. These parameters include rotor axial displacement, relative expansion between the rotor and cylinder, abso...

9. 3500/50 Tachometer Module The 3500/50 tachometer module is a two-channel module that receives signals from eddy current sensors or magnetic sensors (unless otherwise noted) to determine shaft speed, rotor acceleration, or rotor direction. It compares these measurements to user-programmable alarm points and issues an alarm when the alarm point is exceeded. The 3500/50 tachometer module can be pr...
