2. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage protection device, that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or ...

   en.wikipedia.org/wiki/Megger_Group_Limited

   Due to electromagnetic interference, the first Megger insulation testers were built as two separate boxes – one for voltage generation, and one for measurement. They were later integrated into a single device in a Bakelite case, with special foldable handle for driving the dynamo. The most popular was the so-called "Wee Megger" (voltage up to ...

4. Circuit breaker analyzer - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker_analyzer

   A circuit breaker analyzer is an instrument that measures the parameters of a circuit breaker. [1]In 1984, Megger patented a digital circuit breaker analyzer, controlled by a microprocessor. in 2020 few companies develop software to control circuit breaker analyzers from different devices such as computers, tablet computer, smartphones and others.

5. Recloser - Wikipedia

   Single Wire Earth Return Network Protection: SWER network design topology is discouraged in modern electrical engineering due to safety reasons, but due to cost savings it is sometimes deployed. Single Phase Reclosers can be used to improve safety on these lines during fault events. Single Phase Recloser Single Phase Laterals Overcurrent Protection

6. Electrical safety testing - Wikipedia

   en.wikipedia.org/wiki/Electrical_safety_testing

   An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
