Question

How to probe a transformer in a power line coupler?

Answer 1

here is your answer mate :-

Electrical isolation is necessary to protect circuits, equipment, and people from shocks and short circuits as well as to make accurate measurements. Isolation, also referred to as galvanic isolation, means no direct conduction path exists for the current to flow; no physical connection exists. Isolation can be accomplished using electromagnetic, capacitive, or optical devices. While physically and electrically isolating the circuitry from unwanted currents, required signals and power need to be transferred across the separated circuits. To transfer signals, transformers use magnetic flux, capacitive isolators use differential voltage and optocouplers use light to bridge the gap. This article discusses the use of isolation transformers.
