OC90D Semi-Automatic 90kV AC Liquid Dielectric Test Set








The OC60D digital liquid dielectric testing equipment accurately and reliably test the dielectric strength of insulating liquids used in a wide variety of electrical apparatus up to 90kV AC. The safe and easy operation has made Hipotronics OC series the industry standard for decades.

The OC Series is designed to meet testing specifications in all parts of the world and test cells are available for ASTM D877, ASTM D1816 and IEC 156. The rugged yet lightweight and portable design ensures years of trouble-free operation both in the field and in the laboratory.

The Hipotronics OC Series has three pre-programmable rates of voltage rise and automatic termination of voltage upon sample breakdown. A digital memory kilovoltmeter automatically retains the breakdown voltage reading until it is manually reset.
