1.TypesofHiddenFaultsinSecondaryCircuits:
Hiddenfaultsinsecondarycircuitscanmanifestinvariousforms,includingbutnotlimitedto:
a)Wiringerrors:incorrectconnections,shortcircuits,orreversedpolarities.
b)Sensormalfunctions:inaccuratemeasurements,faultyvoltageandcurrentsensors.
c)Communicationbreakdowns:issueswithdatatransmissionandreceptionbetweendevices.
d)Softwareglitches:programmingerrorsandsoftwaremalfunctions.
e)Environmentalfactors:temperaturevariationsandmoisture-induceddegradation.
