Megger: A Megger is a firm that manufactures megohmmeters, a device used to measure insulators’ level of resistance. Because of the numerous industrial applications, it is a very significant instrument. It offers a very high DC voltage for the resistance measurement. It is a portable instrument that is also known as a megohmmeter. It can …
What is the controller action? The controller action is defined as the function of the controller. The controller action determines whether The controller output increases when PV increases above the set point, or The controller output decreases when the PV is increased above the set point. The operator has to select the controller action based …

What is DC Chopper? DC Choppers are static devices that change a set DC input voltage into a variable DC output value. Essentially, it functions as a high speed ON/OFF semiconductor switch. It can be viewed as the DC equivalent of an AC transformer because of how they both operate. The output of the DC …
What is Alternator? A machine that transforms mechanical energy into electrical energy in the form of alternating current at a particular voltage and frequency is referred to as an alternator. Synchronous generators are another name for alternators. The only form of energy that is converted is an alternating current. Most alternators use a spinning magnetic …
Introduction There are many methods for measuring level ;Direct level measurement techniques and indirect methods.in this session we are going to discuss about direct level measurement techniques The direct sensing, in which case the actual level is monitored, and indirect sensing where a property of the liquid such as pressure is sensed to determine the liquid …
