Isolators are safeguarded with a locking system on the external side, or with a lock to stop accidental utilization.The primary applications of the isolator include the following: However, many times, electrical isolators are also used in a fixed position permanently so as to keep the isolation such as in transformers, electrical transmission lines, and grid stations. They are also sometimes used as switches that can be closed and opened based on the requirements and demands. Working with an electrical isolator is very easy and it can be operated in different ways such as semi-automatic, fully-automatic, and manually operated.

A pantograph isolator includes a post insulator and an operating insulator. The pantograph type high power isolator permits the current switchgear installation, and also requires the least space as compared to the above two.
#Substation optical isolator manual
The spin can be done by a lever method at the bottom side of the post insulator and is related to the manual operation of the isolator. The middle one holds a tubular or flat male contact that can further be turned straight by a quick spin of the middle post insulator. The double break type isolator typically consists of three loads of post insulators. The arm contact moreover shifts from its place because of the post insulator rotation upon which these arm contacts are attached. In a single break type isolator, the arm contact is divided into two elements namely the male contact, and female contact. The high power isolators are majorly classified into three types: Besides, the high voltage type isolation such as 1064nm High Power Isolators are used in substations for allowing isolation of tools like circuit breakers, transformers, and so on. These switches are very much used in the distribution of electrical power, industrial areas, etc. They are also recognizable just like isolation switches that isolate the circuits. Isolators are basically types of switching devices that work to make sure that a circuit is not totally triggered to perform the preservation.
