If the average power during generation is zero, why do the analog meters have + and - ?..

The average power during generation is never zero. The load
is never 100% resistive. It has capacitive as well as
inductive components also. The power drawn by only resistive
load is active power and the power drawn by inductive load
is reactive power. The resultant is never zero.

We do have a problem in the company that is one PT connected to PlC which is mean 1 out of 1 in PLC system we do have the PAHH is 55 mbar and PALL 8 mbar with a timer of 15 sec for the PAHH the problem started when PAHH goes more than the set point which is 55 it reached up to 71 but due to timer doesn't trip . We force it and we checked everything nothing there . We replaced the transmitter problem still there the reading goes more than the 55 bar the range for transmitte is 0- 60 mbar . So we did loop check , aculaizing valve , wiring all are okay . What the possible causes for this ???
