Suggestion
1. Check the seal and weld of the oil
tank for oil leakage. If the gas
relay misbehaves due to the oil
level decrease, check whether the
oil level complies with the oil
temperature-oil level curve. Power
off and refill the transformer if
necessary.
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. If there is no gas, check the
secondary loop and whether the
wire post and lead wire of the gas
relay are well insulated.
4. Check whether there is any violent
vibration in the local area,
whether the gas relay leaks oil,
and whether the secondary cable
is corroded.
5. Take a gas sample from the gas
relay. If the gas is colorless,
odorless, and not flammable, it is
air. In this case, identify the air
intake vent and the reason for air
intake, which may be improper oil
charge. If the gas has a peculiar
smell or is even flammable, it
indicates that an internal fault has
occurred. In this case, power off
and maintain the transformer, and
take an oil sample for
chromatography analysis.
6. If the fault persists, contact your
dealer or technical support.
