Generating Unit
Unit or units that generate and produce electric power. Can refer to a single unit that produces power or to multiple generators, reactors and other units that product power.
GFCI
An acronym for Ground Fault Circuit Interrupter, a safety device that breaks a power circuit as soon as it detects current flow of a certain magnitude through the ground return of a power circuit. Also known as GFI.
Ground
The base reference from which voltages are measured, nominally the same potential as the earth. Also the side of a circuit that is at the same potential as the base reference.
Ground Bond Test
Verifies that all conductive parts of a product that are exposed to user contact are connected to the power line ground. The GB test verifies the integrity of the ground connection using a high current AC signal (as high as 30Amps). GB provides a better simulation of how a product will perform under an actual fault condition.

Ground Bond Tester
Ground bond test, or also called ground bond testing, is usually the first electrical test performed to meet safety standards for an electrical safety test specification.
Ground Continuity Test
A test to verify that all conductive parts of a product that are exposed to user contact are connected to the power line ground. GC Test normally performed with a low current DC signal that checks to ensure the ground connection has a resistance of <1Ω.
- H -
Hertz
The unit of measure of frequency, equivalent to cycles per second.
High Limit
The upper value for a test to be considered a PASS. If the measured value is higher than the high limit the test is considered a FAIL. In hipot, leakage current and ground bond tests a high limit is required.
Hipot/Hypot/Hi Pot
High Potential is abbreviated as "hipot" for short. Hipot refers to instruments used to measure electrical insulation in components and devices. Hypot and Hi Pot are variations of Hipot and refer to the same.

Hipot Tester
An instrument for testing dielectric strength using a high potential (voltage); hence, the term "hipot".
