PLUMBING
The product removes oil from the transformer, extracts the gases, analyses the gases
and then returns the oil to the transformer. The locations from which the oil is removed
and to which it is returned are important for the accurate analysis of the gases (see
Figure 8-1 and Figure 8-2).
Figure 8-1: Schematic representation of an installation
The oil is removed from one valve of the transformer (the supply valve) and returned via
another (the return valve). The location of the supply valve should produce an oil sample
that is a well-mixed representation of the transformer oil. The following pages contain
points to consider when choosing where to connect the oil circuit from the transformer
to the product.
