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.
