There is a test swich which will change the polarity of the sensors........
To test the generators reverse power relay to make sure the generator is spinning at the right speed and a fuel issue is not involved. If it is not a fuel issue you need to check the frequency of the electronic load and frequency. If both of these issues are okay check the diesel electronic control unit for dirt and dust. This unit needs to be clean.
A reverse power relay is a directional overcurrent relay. Directional relays are relays that sense power flow in one direction, and include (directional) overcurrent relays, reverse power, and impedance based relays. So a reverse power relay is a directional relay, but a directional relay is not necessarily a reverse power relay.
Reverse resistance should be infinite.
The way to detect if a shunt trip breaker is malfunctioning is to manually trip the breaker. The shunt is usually wired through a auxiliary relay. Make sure that before you trip the breaker that the load can be shut off without taking a production line etc. off line. Trip the auxiliary relay using a test jumper to activate the relays coil. The breaker's handle will move to mid throw and the load will disconnect from the supply power. If the breaker trips then it is working properly. If the breaker does not trip trouble shoot the circuitry that is used to trip the breaker. Usual problem is an open circuit.
No, it will just trip and cut off the power.
Reverse power relays are often used in generator protection to trip breakers if generators are "sucking in" power (since this shouldn't occur, it is a BAD thing when it does). I'm not sure there is a use for reverse power relays beyond this; directional relays looking in a reverse direction are often used in pilotting schemes, though (not "reverse power").
An elevator shunt trip test checks the heat detector placement. It also monitors power and wiring diagram of an elevator.
1) over current trip 2) over volatage trip 3) under voltage trip 4) reverse power trip 5) low frequency trip 6) alternator body earthing
Need to run a fuel pressure test, and check the fuel filter.

Most power drills have a reverse switch near the trigger.

oh no the power had a trip
