Applications
Transformer oil is used as insulating medium in transformer, switchgear and other electrical apparatuses and it also acts as coolant to dissipate heat of the transformer. In addition to these, Insulating Oil serves other purposes like it helps to preserve the core and winding as these are fully immersed inside oil and another important purpose of insulating oil is, it prevents direct contact of atmospheric oxygen with cellulose made of paper insulation used in windings, which is susceptible to oxidation. When insulating oil deteriorates due to aging / contamination which leads to catastrophic event due to flash over in insulation. The voltage withstands capability of oil which often is reduced (which often reduces) to contamination like dirt, water ingress and foreign particles.
OTS-DS series useful for Oil Testing in following equipment’s:
Power and Distribution Transformer
Bushing Instrument Transformer
Switchgear
Capacitors
