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...]
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...]
SF6 Circuit Breaker : Construction, Working, Types, Maintenance & Its Applications
A circuit breaker is one type of protection device used to give protection to the electrical system against fault currents. The main function of the circuit breaker is to stop the flow of current to guard equipment by preventing fire risk. There are different types of circuit breakers. A circuit breaker is significant in electrical systems for security & reliability. If any fault happens, the circuit breaker protects people against electrical shocks … [Read more...]
Circuit Breaker : Circuit, Working, Classification, Differences & Its Applications
The first compact commercial circuit breaker was launched by Stotz in 1923 which combines both the thermal & magnetic protection functions. After that, his team developed a circuit breaker device to replace a fuse. This device has a component, once it is heated it will enable a disconnecting device and once it is cooled, then it is turned on again. There are many companies that have been developing circuit breakers continually which range from … [Read more...]
Vacuum Circuit Breaker : Diagram, Properties, Construction, Working & Its Applications
A circuit breaker is one type of electrical switching device used to control & also protect the power system, either automatically or manually from any harm occurred by short circuits or overload. The main function of the circuit breaker is to obstruct the flow of current once the protective relays notice a fault like electrical fires, shocks, and the electrocution risk. These are classified into different types based on different factors, location of … [Read more...]
Residual Current Device : Circuit, Working & Its Applications
Electricity is incredibly useful everywhere but a lot of people die or injured at home or in industries due to electrical accidents. These accidents can be prevented by installing residual current protection devices in the consumer unit of the house. So these devices can save lives by guarding you & your family against electric shock & provides some protection from fire. This device turns off the electric power supply in a fraction of a second if … [Read more...]
