WebAutomation and control products like contactors, HMIs and PLCs handle most of the operating functions of a machine, system or process. Automated applications rely on a variety of controllers, relays, sensors, timers and modules to start, maintain, adjust and stop machinery and other components. WebThe tap changer function in the transformer is to regulate the voltage level. This is done by either adding or removing turns from the secondary transformer winding. It is the most complex part of the transformer and also an important one. Even the smallest fault results in the wrong power output [6]. The PN number is usually between 28 to 52.
