The iron core multi-point ground fault judgment method is usually
detected from two aspects:
(1) Perform gas chromatography analysis. In the chromatographic
analysis, if the content of methane and olefin components in the
gas is high, and the content of carbon monoxide and carbon dioxide
gas does not change much from the past, or the content is normal,
it means that the core is overheated. To.
When acetylene gas appears in the chromatographic analysis, it
indicates that the iron core has intermittent multi-point
grounding.
(2) Measure the current of the ground wire. You can use a clamp
meter to measure whether there is current on the ground lead of the
grounding sleeve outside the transformer core. When the transformer
core is normally grounded, it is formed due to no current loop. The
current on the ground wire is very small, which is milliampere
level (generally less than 0.3A). When there are multiple points of
grounding, there is a short circuit turn around the core's main
magnetic flux, and the circulating current flows through the turn.
Its value depends on the relative position of the fault point and
the normal ground point, that is, how much magnetic flux is
surrounded by the short circuit turns. Generally up to tens of
amps. By measuring the presence or absence of current in the ground
lead, it can be accurately judged whether the iron core has a
multi-point ground fault.
