![]() ![]() The most commonly used isolator works at the time of the problem. The time it takes to maintain this is when the transformer or circuit breaker is separated from the high transmission line very easily and carefully. Isolator switches are especially used in grid station small substations. Such as reducing the risk of accidental passage of electric current flowing toward the ground. Thus the isolator is used to protect it from the grounding loop. This is used to separate the conductor from the transmission tower, also known as the transmission insulator, as shown in the figure above. Fixed space is installed to keep space like grid station separate Whose figure is as follows. An electrical Isolator can also be used as a switch in some circumstances which can be turned on or off as required.īut often electrical isolator to the transmission line, transformer. The function of the Electrical Isolator is very simple and can be operated in various ways such as fully automatic semi-automatic or manually operated. ![]() Suggested Read: Electrical Substation Components and Their Workings The isolator is usually mounted at the end of the transmission line so that the circuit breaker can be easily repaired without any risk. ![]() It is not advisable to operate this in the timeline in which the current is flowing and it has not yet become a switch that can be operated in live operation. The isolator switch is always used to open the electrical circuit in the no-load condition. The time required is to complete the electrical circuit i.e. Isolators can be defined by covering something. Suggested Read: What is Suspension Insulator? | The Definitive Guide What is Electrical Isolator? The isolator can be operated automatically or manually. Sub-voltage type isolation switches are used in the substation to allow the separation of equipment such as transformers and circuit breakers. This switch is used in various places like industrial power transmission lines etc. This acts as insulation to separate the parts of the circuit. Its main function is to ensure that no current flows in the circuit during protection. The insulator is a type of switching device.
