ANSI/IEEE Minimum active-power relay form
IEEE-library form of minimum active-power relay: a minimum active-power relay operates according to a configured low active-power condition.
In plain English
What does ANSI/IEEE Minimum active-power relay form mean?
This reference locates minimum active-power relay in Autodesk's IEEE-oriented miscellaneous relays family. A minimum active-power relay operates according to a configured low active-power condition. The measurement direction and enable logic determine what low power means in the control sequence. The public library uses HCR1F43 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Trace the measured quantity or initiating control signal separately from the output contacts. The device tag links the sensing or operating element to the controlled circuit; settings, reset behaviour and the actual terminal arrangement belong in the selected equipment documentation.
What the drawings help you do
Identify the directional convention before evaluating the threshold. Minimum active power and reverse power are different operating criteria. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.
