Optical Instrument Transformer
An optical instrument transformer measures electrical current or voltage through an optical sensing mechanism and delivers a proportional signal to receiving equipment.

Product & engineering
Understand the product.
A fibre-optic current arrangement places the sensing path around the primary conductor and connects it optically to an interrogation unit. The source sends light to the head; returned light is detected and processed to recover the current-related change. A passive sensing head can be separated from active electronics, but the complete measurement system still depends on its light source, detection, processing and auxiliary supply.
Removing the conventional ferromagnetic current-transformer core avoids that core's saturation mechanism. It does not remove dielectric, temperature, bandwidth, calibration or output limits. Current and voltage sensing require different physical couplings. An electronic voltage divider with an optical communication link should not automatically be classified as a direct optical voltage sensor.
Output may be analog or digital according to the offered system. A digital process-bus installation may add a merging unit, clock synchronization and receiving relays or meters. Sampling rate, delay, time alignment, redundancy and behaviour during loss of power or signal are therefore integration questions. An optical current system can also consolidate a conventional voltage-transformer signal without making that voltage measurement optically sensed.
What turns activity into demand
Trace the physical measurement through to the relay or meter instead of judging the product by its fibre connection alone. The scope concerns optical current or voltage measurement systems. Optical communications alone do not define an optical sensor; electronic dividers, Rogowski systems and receiving relays need separate identification within the package.
The commercial boundary
The scope concerns optical current or voltage measurement systems. Optical communications alone do not define an optical sensor; electronic dividers, Rogowski systems and receiving relays need separate identification within the package.
