Positron High Voltage Live Line Testers For Porcelain,
Polymeric and Composite Insulators
Protect the Safety of Personnel and Prevent Costly Power Outages and Downed Power Lines
- Safe to use: Does not make electrical contact with the lines or insulators
- Proven electric field detection technology methodology
- Does NOT rely on line of sight, heat (Infrared), corona discharge (Ultra Violet) or acoustics with limited reliability
- 100% reliable to detect all conductive defects including early stage defects and contamination
Safe, Simple and Accurate
The Positron Insulator Testers are revolutionary, simple to use lightweight tools that record defects and dangerous conditions on energized suspension insulators, station posts, bushings and lightning arresters. They measure the electric eld along the insulators, record the electrical eld and all conductive insulator defects. They can be used on all types of insulators (Porcelain, Composite, Glass* for contamination assessment, etc.) and are safe, simple and accurate.
The operational integrity of high voltage insulators is a priority, particularly when you consider that a damaged, electrically de cient insulator can lead to system failure, serious injury, or loss of life. Positron’s Insulator Testers are a major advance in insulator maintenance, they allow for the safe and reliable evaluation of high voltage insulators. Simply slide the tester sled along the insulator or insulator string and the results are automatically processed and available.
