Condition Monitoring System A condition monitoring system (CMS) is a maintenance approach for forecasting the health of equipment or machines along with sensor data to measure vibration and related parameters with upgraded machine monitoring software. This condition monitoring system permits or allows the plant operators to remotely monitor and control the health of each and …
What is Universal Motor? A unique kind of motor called a universal motor is made to operate on either a single phase of AC power or a DC supply. These motors typically have series wound armatures and field windings, which results in strong starting torque. Because of this, universal motors frequently arrive pre-installed in the …
What is a Relay? Relays are switching devices that are used to control the flow of electricity, and by extension, the circuit to which it is directed. By managing the current flow through an electromechanical assembly or a solid state circuit, a relay can be used to switch a circuit and activate/deactivate among several connected …

High Rupturing Capacity (HRC) Fuse: The HRC fuse or High Rupturing Capacity fuse, works similarly to a standard fuse in that the fuse wire can only carry a set amount of short circuit current. It burns if the flow is higher than this. Glass or any other form of chemical component is used to make …

What is Neutral? The term “neutral” refers to a point with zero potential. Because each single phase load requires the current return channel, the perfect ground point is called Neutral. To maintain a continuous flow, the electron should travel from source to load to source. As a result, it necessitates a flawless return path. If …
What is an ELCB? Earth Leakage Circuit Breakers are safety devices that provide additional protection against earth leakage. ELCB is employed in places where the earth impedance is high. The primary objective of these devices is to reduce the risk of shock in the event of a current flow to the earth. When energy “leaking” …
Introduction In order to avoid unexpected breakdowns, costly repairs and subsequent losses due to motor downtime, it is important that the motor is fitted with some sort of protective device. Generally speaking, motor protection can be divided into the following 3 levels: • External protection against short circuit in the whole installation. External protection device …
Introduction Motor protection safeguards the motor, the supply system and personnel from various operating conditions of the driven load, the supply system or the motor itself. Motor protection categories include — Overcurrent Protection –Overload Protection –Other Types of Protection. • The National Electrical Code requires that motors and their conductors be protected from both overcurrent …
