Applications of Isolator Switch
An insulator is one type of detaching switch which works under the condition of off-loading. It separates the circuit part in which the error takes place from the power supply. Isolators are applicable for high voltage devices like transformers. The main function of the Isolator is, it blocks the DC signals & allows the AC signals to flow.
The applications of Isolators involve high voltage devices such as transformers.
These are protected with a locking system on the external or with a lock to stop accidental usage.
Isolator in Substation: When a fault occurs in a substation, then the isolator cuts out a portion of a substation.
When a fault occurs in a substation, the isolator cuts out a portion of a substation. The other apparatus works without any intrusion.
The circuit breaker is like an MCB or ACB that trips the complete system if there is an error occurs
Thus, this is all about an overview of the electrical isolator. The characteristics of this isolator include it is an offload device, operated manually, De-energize the circuit, entire isolation for secure maintenance, includes a padlock, etc
