GLOSSARY
A transformer with primary and secondary windings physically separated by
ISOLATING TRANSFORMER design to permit magnetic coupling between isolated circuits whilst minimizing
electrostatic coupling.
A load in which the relationship between current and voltage is directly
LINEAR LOAD
proportional.
KW Kilowatt, 1,000 watts.
KWH Kilowatt hour, one kilowatt for one hour.
Kilovolt-ampere, or thousand volt-ampere. When multiplied by the power factor,
KVA
will give kilowatts, or KW. Most transformers have their rating expressed in KVA
Conductive material placed around a transformer’s coils to attenuate stray
MAGNETIC SHIELDING
magnetic fields.
A method of temperature regulation in which the normal convection of ambient
NATURAL CONVECTION
air surrounding the transformer will provide its only cooling.
NOMINAL VOLTAGE The normal designed voltage level.
NON-LINEAR LOAD A load in which the relationship between current and voltage is not directly
proportional.
The relationship between voltage, current and resistance. The current in an
OHM’S LAW electrical circuit is directly proportional to the voltage and inversely proportional
to the resistance.
OPEN FRAME A method of transformer construction.
