H-20 – Also referred to as “HS20-44” or “H20-44” Bridge Loading. H20 Loading refers to a maximum front wheel loading of 8000 lbs and a maximum rear wheel load of 16,000 lbs with an impact factor of 30% added (16000 x 1.30) for a total maximum wheel loading of 20,000 lbs.
H2 – Hydrogen.
H20-44 – See “H20”.
Half-duplex communications – A communications system in which data can travel in both directions, but only in one direction at a time.
Hard Drawn – Wire that has been drawn to its specific size and not annealed.
Hard Line – A Steel Pulling line. Also see Bull Line.
Harmonic – A sinusoidal component of the voltage that is a multiple of the fundamental wave frequency.
Harmonic Distortion – The presence of harmonics that change an AC waveform from sinusoidal to complex. They can cause unacceptable disturbance to electronic equipment.
Hazard Risk Category – Categories defined by NFPA 70E-2004 to explain protection levels needed when performing tasks. The values range from 1 to 4. ATPV rated PPE is required for categories 1 through 4 as follows: 1- 4 cal/cm²; 2- 8 cal/cm²; 3- 25 cal/cm²; 4- 40 cal/cm².
Heat Run Test – A test that is used to determine the increase in operating temperature at a given load.
Helical – Wrapped in a spiral fashion. Refers to the way the strands of a conductor are laid.
Henry – The meter-kilogram-second unit of inductance, equal to the inductance of a circuit in which an electromotive force of one volt is produced by a current in the circuit which varies at the rate of one ampere per second.
Hertz – 1) A unit of frequency equal to one cycle per second. 2) In alternating current, the changing of the negative and positive poles.
HID – High Intensity Discharge.
High Intensity Discharge (HID) Lamp – An electric discharge lamp in which the light producing arc is stabilized. Examples of HID lamps include High Pressure Sodium, Metal Halide and Mercury Vapor.
High Pot – A test done to confirm the reliability of an insulation system where a high voltage is applied.
High Pressure Sodium (HPS) Lamp – A High Intensity Discharge light source in which the arc tube’s primary internal element is Sodium Vapor.
High Voltage – An electrical system or cable designed to operate between 46kv and 230kv.
High Voltage System – An electric power system having a maximum roo-mean-square ac voltage above 72.5 kilovolts (kv).
High-speed reclosing – A re-closing scheme where re-closure is carried out without any time delay other than required for deionization.
Hooks – See “Climbers”.
Hookstick – An insulated stick, usually made of fiberglass, that is used to work energized overhead conductors and operate electrical equipment.
Horsepower – A unit of work. When used to show power usage, one horsepower is equivalent to 746 watts.
Hose – Slang for “Line Hose”.
Hot – Refers to an energized conductor or apparatus.
Hot Arm – A device that is used to temporarily extend a conductor beyond the cross arm it was on.
Hotstick – An insulated stick, usually made of fiberglass, that is used to work energized overhead conductors and operate electrical equipment that is overhead, underground and pad mounted.
HPS – High Pressure Sodium.
HRC – High Rupturing Capacity (applicable to fuses).
HS20-44 – See “H-20”
HS285 (TM) – Aluminum Conductor, Steel Supported with Extra High Strength Steel Core. HS285 is a Trademark of Southwire Company.
HSR – High Speed Re-closing.
HV – High Voltage.
Hybrid Photovoltaic System – A photovoltaic system that includes other sources of electric generation such as wind or fossil fuel.
Hydrometer – A float type instrument used to determine the state-of-charge of a battery by measuring the specific gravity of the battery electrolyte (i.e., the amount of sulfuric acid in the electrolyte).
