Isolators Testers

Positron High Voltage Live Line Testers For Porcelain & Polymeric 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.

Reliably used and validated by 50 major Power Utilities worldwide

On higher voltage transmission lines there are power outages. In addition to lost revenues, loss of power to critical services (such as hospitals, re, police), negative impact on their reputation, damage, emergency repair costs, loss of revenue the utilities have to pay very stiff penalties. They do not have a maintenance culture so this is a new concept for them. It is necessary to educate them on the concept that this is like buying re insurance on your home. It will reduce power outages.
