What is a safety barrier? Safety barriers are intrinsically safe Shunt diodes. These barriers are passive network devices that use Zener diodes, resistors, and fuses to deflect surplus or extra electrical energy to the ground via earthing systems. To prevent sparking or overheating of plant equipment located in hazardous areas. Safety barrier is a circuit …

A balanced beam type relay uses two electromagnets at either end of a beam as an alternative to an attraction armature type relay. The first magnetic produces operating torque, and the other magnetic supplies retraining torque. The beam is positioned in the middle & typically maintains a horizontal posture. Construction of Balanced Beam Relay: Based …
What is Movable Coil Relay? The most sensitive electromagnetic relay is the moving coil relay, often known as a polarised DC moving coil relay. This relay is frequently used for sensitive and accurate measurement for distance and differential protection due to its high sensitivity. Relays of this type are by default suitable for DC systems. …
What is a Multimeter? An electronic device called a multimeter is used to measure circuit resistance, amps, and voltage. Engineers can use multimeters to check voltage, resistance, and electrical current levels by connecting two leads to various electrical system components. This device is also sometimes referred to as a volt-ohm metre or volt-ohm-milliampere (VOM). The …
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 NO/NC notion is essential. The phrases “normally open” (NO) and “normally closed” (NC) are used to describe the states that switches, sensors, or relay contacts are in when their coils …
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, readily measured values that are utilised for high voltage system metering, protection, and control. Normally, it is impossible to detect the line voltage or current in a high voltage system. …
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 break precisely at a reverse voltage without being damaged. Once these diodes are linked in series, they can be used in high voltage, inductive, protective circuits. An avalanche diode will …
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 normal supply voltage is quite high for a brief period of time. In contrast to DC motors, there is no back emf, which results in a large beginning current. When …
