Generally, both electromechanical and solid-state relays are similar, but solid-state relays electrically isolate the low-voltage input from the output that simply switches and controls an electric load. Electro-mechanical relays have a limited contact life cycle, so they have slower switch speeds, particularly in contractors and large power relays, whereas solid-state relays do not have such limitations. The solid-state relay (SSR) doesn’t have any moving … [Read more...]
Cycloconverter : Circuit, Working, Types, Control Strategies, Characteristics & Its Applications
A power supply is used to change the electric current from a source to the voltage, frequency & current to power the electric load. Sometimes these are called electric power converters. Power supply is classified into two categories; AC & DC power supply. We know that AC power is more economical and it can be used for transmission thus most of the electrical devices or machines run on AC power. However, the typical frequency & voltage supplied … [Read more...]
Electric Flux : Formula, Types, Properties, Different Surfaces & Its Applications
Electric flux is a basic concept within physics that assists us in understanding as well as measuring the electric field supplied throughout a given surface. This is an electric field property in the number of electric force lines intersecting a given region. This flux gives a means to explain electric field lines flow throughout an area. Electric field lines are simply considered to originate on positive electric charges & to terminate on negative … [Read more...]
Capacitor Start Motor : Circuit, Working, Phasor Diagram, Characteristics, Advantages & Its Applications
A capacitor motor is a single-phase induction motor that has two windings; the main winding and auxiliary winding. The main winding gets energy from the power line directly whereas a secondary winding like auxiliary winding gets energy throughout a capacitor. This kind of motor has some benefits like higher starting and running torque. The currents within this motor’s two windings will differ in phase & producing torque. There are three kinds of … [Read more...]
Electrical Hazard : Causes, Types, Do’S and Dont’S, Examples & Control Measures
In an electric field, working with electricity is not safe when workers don’t identify and control electrical hazards properly. However, lack of knowledge, failure to identify potential hazards, and not enough training cause electric shocks, fire hazards, and explosions. Most of these hazards were caused mainly by direct contact with machines, overhead transmission lines hand-carried metallic objects & contact with tools. So protecting ourselves … [Read more...]
Earth Leakage Circuit Breaker : Circuit, Working, Types, Differences, Advantages & Its Applications
The flow of current from the live conductor to the earth throughout an unintended lane is known as earth leakage. So it may supply in between their poor insulation (or) throughout a person’s body & cause electrical shock. The effect of this electrical shock causes damage to a device or a person if the leakage current goes beyond 30mA. So, protection devices like ELCB or earth leakage circuit breakers are used to separate the power source whenever … [Read more...]
Voltage Detector : Circuit, Working, Types, Differences, Advantages & Its Applications
A voltage detector is a significant electrical safety tool that is used by electricians or utility workers who work with electrical systems & equipment. In the electrical industry, these devices play a key role in detecting the occurrence of electrical energy within conductors, electrical equipment & power lines. So they provide an effective, secure & simple method to verify whether any electrical device is de-energized or not before any work … [Read more...]
Earth Tester : Construction, Working, Types, Differences, Specifications & Its Applications.
The first earth tester was invented in the year 1950 by Evershed and Vignoles Meggers who made the initial insulation as well as earth resistance testers. Analog grounding tester like М416 is the most frequently used in the USSR. Many organizations from the 21st century manufacture digital earth resistance meters as well as testers. The main function of this instrument is to decide the capability of the grounding for an electrical system. By a NEC … [Read more...]
Miniature Circuit Breaker : Construction, Diagram, Working, Types, Wiring & Its Applications
Protection is the main concern while choosing any electrical device or appliance because when the power varies or excess current supplies, then it causes harm that results in a short circuit or an overload. So, it is necessary to integrate a device as a protection element to give over current protection to the device. The most common safety device used for protecting the circuit is a fuse which includes a metal wire/strip that dissolves whenever an … [Read more...]
Temperature Switch : Construction, Circuit, Working, Types & Its Applications
Temperature sensors and temperature switches are the two most significant devices utilized in different industries & applications for monitoring as well as controlling temperature. But the main difference between these two is; that a temperature switch is an electronic device used for opening or closing an electrical circuit whenever it reaches a particular temperature whereas a temperature sensor is a device used to measure its surrounding temperature … [Read more...]
