A fully insulated wire or bundle of wires installed underground or overhead.

An element in lead-acid batteries that hardens the plate material.

The procedure that determines the location of scale graduations on an instrument by comparison to a standard series of values.

An electrical device that contains two conductive plates separated by a dielectric (insulator or nonconductor of electricity) substance. Installed in substations, on poles, and inside facilities to correct unwanted conditions in an electrical system. It stores small amounts of energy, detours high-frequency transients to ground, and resists changes in voltage. It helps improve the efficiency of the flow of electricity through distribution lines by reducing energy losses and increasing the power factor.

The maximum load of electricity that equipment can carry.

Slice of carbon typically used as a resistor.

The former Computer Business Equipment Manufacturers Association; replaced by the Information Technology Industry Council (ITIC).

A set of curves developed by the Computer Business Equipment Manufacturers Association (CBEMA) that represents the withstand capabilities of computers in terms of the magnitude and duration of a voltage disturbance. It was a standard for measuring the performance of all types of equipment and power systems until replaced by the Information Technology Industry Council (ITIC) curve.

The voltage required for storage batteries to maintain their maximum charge.

An ac-to-dc converter that provides power to a UPS inverter and maintains the battery reservoir charge.

Installed as a temporary...
