Different types of meters are used in the MCC panel for indicating the status of the panel.Mainly three types of meters are used. Ammeter, Volt meter, Watt meter, Energy meter. Analog and Digital type meters are using nowadays. Ammeter An instrument used for measuring the current flow in the circuit is called ammeter. It should be …
CONTROL PANEL Control panel is a cabinet which contains electrical components to control the motors and equipments. CABLES Cables are used for the interconnection. Two types of cables are used. Power cable and control cable. 1. Power cables (which is used to connect the motor to panel component and panel to main supply) 2. Control …

Define Circuit Element? An electric circuit is made up of many circuit components joined together to provide a closed path that allows electricity to flow. An electrical circuit element is the mathematical representation of an electrical device and is entirely defined by the relationship between voltage and current. As a circuit element is the most …
Ohm’s law (which should be familiar) is a very useful rule. Note that it only applies to resistive loads however. The impedance of other passive components may vary with (e.g.) frequency (e.g. capacitors) and many components do not obey this rule at all (diodes, transistors etc.). Resistance determines how much charge flows per second when …
Basics of Electrical. Instrumentation engineer must be thorough with electrical fundamentals. What is … Charge? Charge is measured in coulombs and is the amount of “electricity” present (or flowing). Charge can be positive or negative. Like charges repel each other. Unlike charges attract each other. In the vicinity of a charge there is an electric …
