Alarm Possible Cause
Severity
Major 1. The gas loop is

misbehaves.
4. A short circuit
occurs in the
transformer.

Suggestion
1. Check the secondary loop and
whether the wire post and lead
wire of the gas relay are well
insulated.
2. When the transformer is being
repaired or installed, the oil
charge method is improper. As a
result, the gas in the upper part of
the conservator is not exhausted
as required. Power off the
transformer and refill it until the
oil is over the conservator. Then,
release oil to an appropriate level
by referring to the oil
temperature-oil level curve.
3. Check whether there is any violent
vibration in the local area,
whether the gas relay leaks oil,
and whether the secondary cable
is corroded.
4. Check whether there are obvious
bumps and dents on the shell of
the transformer, whether the
container leaks oil, and whether
the pressure relief device is
sprayed with oil. If yes, it indicates
a serious internal fault.
5. If the fault persists, contact your
dealer or technical support.
1. Check whether the transformer is
overloaded. If yes, the high
winding 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 the
same as that on the winding
thermometer. If no, rectify the
fault on the winding thermometer.
4. If the fault persists, contact your
dealer or technical support.
