The Motwane Manufacturing Company Private Limited

The HVT Series Hi‑Pot Test Set is a high‑performance testing solution designed to evaluate the dielectric strength and insulation withstand capability of electrical equipment. The system generates AC, DC, or combined AC+DC high voltage, eliminating the need for separate test kits. The equipment is available in multiple voltage ranges from 5 kV to 70 kV and is designed to deliver reliable, accurate, and safe high‑voltage testing. It features adjustable output voltage, selectable tripping current, and digital timer control for precise test duration. The system is equipped with advanced safety features including zero start interlock, earth fault interlock, door interlock, and overload protection, ensuring maximum operator safety. Its wheel‑mounted design enables easy movement in field conditions and testing environments.
