Solution Overview

Problem

Current high-voltage electrical equipment distribution facilities require multiple measuring, control, and protecting means for each piece of equipment, leading to increased space, wiring complexity, and costs due to specific connection requirements and on-site installation challenges.

Innovation Solution

A high-voltage insulated adapter allows connection of measuring, control, and protecting means with a standard bushing to any bar of the high-voltage electrical equipment, using an insulating body with conductive layers to ensure uniform electric field distribution and prevent corona effects, and can be installed with either male or female bushings, minimizing the need for multiple units and reducing installation errors.
