A
ANTISEIZE COMPOUNDA silicon-based, high-temperature lubricant applied to threaded components to aid in their removal after they have been subjected to rapid heating and cooling [4]. |
APERTUREAPERTURE—See SLOT [11]. |
APLALLOWANCE PARTS LIST (APL)—Repair parts required for units having the equipment/ component listed [14]. |
APOGEEThe point in the orbit of a satellite the greatest distance from the earth [17]. |
APPARENT DRIFTThe effect of the earth's rotation on a gyro that causes the spinning axis to appear to make one complete rotation in one day. Also called APPARENT PRECESSION or APPARENT ROTATION [15]. |
APPARENT POWERThat power apparently available for use in an ac circuit containing a reactive element. It is the product of effective voltage times effective current expressed in volt-amperes. It must be multiplied by the power factor to obtain true power available [2]. |
APPARENT PRECESSIONAPPARENT PRECESSION—See APPARENT DRIFT [15]. |
APPARENT ROTATIONAPPARENT ROTATION—See APPARENT DRIFT [15]. |
ARC EXTINGUISHERThe part of a circuit breaker that confines and divides the arc which occurs when the contact of the circuit breaker opens [3]. |
ARMATURE(1) In a relay, the movable portion of the relay [3]. (2) The windings in which the output voltage is generated in a generator or in which input current creates a magnetic field that interacts with the main field in a motor [5]. |
