OTS - Oil Breakdown Voltage Test Kit

A fully Automatic Microprocessor based kit designed with features.

Preprogrammed international test standards

Bluetooth enabled device

Internal memory for 100 test result

OTS - 60A/80A/100A


OTS-A series is fully automatic microprocessor based kit designed with advanced features to measure breakdown voltage of insulation oil. It can measure breakdown voltage more accurately & precisely due to quick sensing ability of kit. The OTS-A Series has pre-programmed worldwide acceptable standards with user friendly customized standards. The large LCD display with touchpad for easy operation. It is provided with internal memory for 100 data storage & inbuilt printer for onsite report. The kit is protected from damage by automatic detection of poor input ground. The acrylic oil test vessel provide with adjustable electrode gap setting to test as per standards. The portable voltage calibrator useful for onsite calibration which saves cost & time of user.


Transformer oil serves mainly two purposes one it is liquid insulation in electrical power transformer and two it dissipates heat of the transformer, acts as coolant. In addition to these, this oil serves two purposes, it helps to preserve the core and winding as theses are fully immersed inside oil and another important purpose of this oil is, it prevents direct contact of atmospheric oxygen with cellulose compromised due to aging / contamination, it leads to catastrophic event due to insulation flashover. The voltage withstands capability of oil often reduced due to contamination. The contamination can be due to dirt, water ingress and particulate cellulosic fibers.
