2. Electric fence - Wikipedia

   en.wikipedia.org/wiki/Electric_fence

   A "stun–lethal" fence may also consist of two fences; one set of wires forming a conventional pulsed DC non-lethal fence, the second set (interleaved with the first) forming a 6.6 kV AC lethal fence, energized when the DC fence detects an intruder. Alternatively it may consist of a single, AC or pulsed DC fence capable of running in "safe ...

3. Electrical safety testing - Wikipedia

   en.wikipedia.org/wiki/Electrical_safety_testing

   A survey without touching anything, and looking at the electrical installation or product before starting any electrical testing. A visual inspection seeks to identify damaged insulation, disconnected wires, incorrect installation, and any other visual issues. Dead testing. Continuity test: a test to check the wiring is correct

4. Dielectric withstand test - Wikipedia

   en.wikipedia.org/wiki/Dielectric_withstand_test

   An insulation test set; in this pattern, a hand-cranked generator provides the high voltage and the scale is directly calibrated in megohms. Voltage withstand testing is done with a high-voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test.

5. Stray voltage - Wikipedia

   en.wikipedia.org/wiki/Stray_voltage

   Reliability of the test can be affected if the user is at an elevated potential him/herself, or if the user is not making firm contact with a bare hand on the reference terminal of the tester. Capacitive coupling is the mechanism used by electrical tester pen devices. Because the capacitance between an object and a current source is typically ...

6. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in ...
