Oil
temperatur
e alarm
1. Transformer overload
operation. Overload operation
may result in a high oil
temperature alarm.
1. Check if the transformer is
overloaded.
2. The heat dissipation channel
is blocked.
2. Check the transformer heat
dissipation channel for foreign
matter jams.
3. The secondary circuit causes
a false alarm.
3. Check the actual oil
temperature of the transformer to
see if it is a false alarm.
Oil
temperatur
e trip
1. The transformer is overloaded.
1. Check if the transformer oil
level is too low.
2. Internal fault of the
transformer.
2. Check if the temperature
sensor is abnormal.
3. Transformer secondary circuit
failure.
Long-term overload operation will
cause the transformer
temperature to continue to rise,
resulting in overcurrent and high
voltage tripping.
3. Check the load on the
transformer.
Check the load through the
internal current meter of the low
voltage cabinet.
If the trip occurs due to an
overload, it is recommended to
reduce the running load.
