Porcelain Insulator Tester

The Positron Porcelain Insulator Tester is a revolutionary instrument capable of determining the condition of all types of porcelain insulator strings, including critical suspension insulators, and making a determination if it is safe for live-line transmission work on AC transmission power lines of 69 kV to 1,000 kV.

A very simple procedure produces a graphic result that enables an on-the-spot determination if an insulator is safe or not.

Porcelain Insulator Tester

Positron’s Porcelain Insulator Tester has been sold around the world since the early 1990s and is the only product of its kind that can determine the condition of Porcelain Suspension Insulators by sensing the insulator’s surrounding Electric Field.

The testers are not impacted by environmental conditions and provide a clear indication when a critical or more-severe-than-critical defect is present.
