The word "Isolator" is spelled with a silent "s" and pronounced [ˈaɪ.sə.leɪ.tər]. The "i" is pronounced with a long "i" sound [aɪ], followed by "s" which is not pronounced, then "o" with a short "o" sound [ɑ], "l" with a clear "l" sound [l], "a" with a short "a" sound [ə], "t" with a clear "t" sound [t], and finally "o" with a short "o" sound [ɑ]. The word refers to a device or object that isolates or separates something from its surroundings.
An isolator, commonly referred to as an isolation device, is a mechanical or electrical device designed to disconnect a circuit or system from its source of power or signal. The primary function of an isolator is to provide a physical barrier or insulation between the circuit being isolated and the rest of the system.
In electrical engineering, an isolator is typically used to disconnect a specific section of a circuit for maintenance or repair purposes. It is commonly found in power distribution systems where it plays a critical role in ensuring the safety of personnel and equipment during maintenance activities. By isolating a particular circuit or equipment, an isolator prevents the flow of electrical energy or signal and eliminates the risk of accidental electrocution or damage to the sensitive apparatus.
Mechanical isolators, on the other hand, are used to physically separate two components or systems that need to be isolated. These are commonly found in industrial applications where vibration, noise, or contamination control is required. Mechanical isolators are often made from rubber, springs, or air cushions and are used to decouple machinery or equipment from its surroundings, reducing the transmission of unwanted vibrations and ensuring smooth and stable operation.
In summary, an isolator is a versatile device used to disconnect electrical circuits or create physical separation between different components or systems. Its primary purpose is to safeguard against electrical hazards, allow maintenance activities, and provide vibration or noise control in various applications.
The word "isolator" is derived from the Latin word "isōlātor", which itself is derived from the Latin verb "isōlāre", meaning "to isolate" or "to detach". The Latin word was formed by combining the prefix "i-" (meaning "in", "into", or "on") with the word "sōlus" (meaning "alone" or "only"). Therefore, the etymology of "isolator" reflects its meaning as something that is used for isolation or detachment.
