The designation used to indicate that a transformer will deliver rated KVA when connected to a voltage source which is higher than rated voltage. Full capacity below nominal taps. Same as FCAN except that the taps are below rated voltage. This has the effect of increasing the transformer rating. A device for filtering and absorbing moisture from oil.
Liquid is force-circulated through absorbent filter pads.
A pliable conductor designed to compensate for thermal expansion and contraction, or reduce the transmission of objectionable noise. The number of times an AC voltage will alternate from positive to negative and back again within a specified period of time, usually expressed in cycles per second and identified as Hz as in 60 Hz. Tap that is designed to deliver the rated capacity of the transformer. . Return to top of page . A term for AC frequency in cycles per second.
