Difference Between NO and NC Contacts
Logic is constructed based on the open or closed state of switches, sensors, or relays in every control circuit and automation system. Thus, understanding the...
What is Capacitive Voltage Transformer?
CVT Capacitive Voltage Transformer is a step-down transformer that changes high voltage into low voltage. Capacitor Voltage Transformers transform transmission class voltages into uniformly low,...
How does the Avalanche Diode works?
What is an Avalanche diode? A reverse breakdown region-operating diode is referred to as an avalanche diode. The fundamental purpose of these diodes is to...
Three-phase induction motor starting methods
An induction motor resembles a poly-phase transformer with a shorted secondary circuit. As a result, the initial current drawn by the primary in transformers at...
What is the purpose of Wave Trapper in Power System?
Wave Trapper: A wave trap is an interference positioned on the transmission line that stops a high-frequency waveform from entering a low-frequency device. A cylindrical...
How Change-Over Switch Works?
