    OTS-A series is a fully automatic transformer oil BDV test kit designed with advanced technologies to measure the electrical breakdown strength of insulating oil. OTS-A has a quick sensing ability to measure accurate breakdown voltage. The OTS-A series is compliant with national & international standards for test sequences and also has user friendly customized test sequences. The series comes with a large LCD display with a touchpad for easy operations. It is provided with internal memory to store up to 100 tests & an inbuilt thermal printer for on-site report printing. As for safety, our transformer oil testing machine series has an open ground detection feature to avoid damage. The molded oil test vessel is suitable to test minerals, ester & synthetic oils and comes with an adjustable electrode gap setting to conduct tests as per standards. The portable voltage checker is useful for onsite calibration and verification.  Ask for a quote to know the Motwane transformer oil BDV test kit price.

    OTS-A series has a Bluetooth connectivity module with MOT-WARE mobile app for remote access to testing data & storage in the cloud for further analysis & record purposes.


    Transformer oil is used as an insulating medium in transformers, switchgear, and other electrical apparatus and also acts as a coolant to dissipate the heat of the transformer. In addition to these, insulating oil helps to preserve the core and winding as these are fully immersed inside the oil. It prevents the direct contact of atmospheric oxygen with cellulose insulation made of paper used in windings which is susceptible to oxidation. When insulating oil deteriorates due to aging or contamination, it can even lead to a catastrophic event due to a flashover in insulation. The voltage withstands capability of oil is often reduced due to contaminants like dirt, water ingress, and foreign particles.
