2. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   Two major sensing devices based on Faraday’s law are Current transformers (CTs) and Rogowski coils. These sensors provide an intrinsic electrical isolation between the current to be measured and the output signal, thus making these current sensing devices mandatory, where safety standards demand electrical isolation.

3. Earth-leakage circuit breaker - Wikipedia

   en.wikipedia.org/.../Earth-leakage_protection_device

   Disadvantages of voltage-sensing devices over current-sensing: A wire break in the fault to load section, or in the earth to ground section, will disable operation of the devices. Requirement of an additional third wire from the load to the devices. Separate devices cannot be grounded individually.

4. Fiber-optic current sensor - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_current_sensor

   A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Utilizing a single-ended optical fiber wrapped around the current conductor, [1] FOCS exploits the magneto-optic effect (Faraday effect). [2] The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.

5. Four-terminal sensing - Wikipedia

   en.wikipedia.org/wiki/Four-terminal_sensing

   Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

6. Photoelectric sensor - Wikipedia

   en.wikipedia.org/wiki/Photoelectric_sensor

   A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are largely used in industrial manufacturing. There are three different useful types: opposed (through-beam), retro-reflective, and proximity-sensing (diffused).
