2. Electronic transformers
2.1 Current transformers
Electronic current transformers are of interest in high voltage (HV) applications, where they combine the measuring qualities of magnetic transformers with the insulating properties of optical fibers. A typical configuration is shown in figure 5 . A distinction is made between measuring equipment, at line potential, a fiber optic link, ensuring insulation, and receiving equipment, at earth potential.
The primary current I p is measured by means of a current transformer, which does not have to perform an insulation function, and whose secondary outputs to a measuring shunt. The collected...
