Suggestion
1. Check the secondary loop for false
actions. If the relay action is
correct, refill oil to the
transformer.
2. Check whether the capsule is
damaged. If yes, replace the
capsule.
3. If the fault persists, contact your
dealer or technical support.
1. Check whether the transformer is
overloaded. If yes, the high oil
temperature alarm is generated in
some scenarios.
2. Check whether a false alarm is
generated based on the cable
connection of the secondary loop.
3. Check whether the temperature
on the monitoring device is
consistent with that on the oil
surface thermometer. If no, rectify
the fault on the oil surface
thermometer.
4. If the fault persists, contact your
dealer or technical support.
