Why is insulator testing so important?

ThePositron Insulator Testers are revolutionary, simple to use lightweight tools that record defects anddangerousconditionsonenergizedsuspensioninsulators,stationposts,bushingsandlightningarresters.Theymeasuretheelectricfieldalongthe insulators,recordtheelectricalfieldandallconductive insulatordefects. They can be used on all types of insulators (Porcelain, Composite, Glass* for contaminationassessment,etc.)andaresafe,simpleandaccurate.

Theoperationalintegrityofhighvoltageinsulatorsisapriority,particularlywhenyouconsiderthatadamaged,electricallydeficient insulatorcan leadtosystemfailure,serious injury,or lossof life.Positron’s InsulatorTesters are amajor advance in insulatormaintenance, they allow for the safe and reliable evaluation ofhighvoltageinsulators.Simplyslidethetestersledalongtheinsulatororinsulatorstringandtheresultsareautomaticallyprocessedandavailable.

Electric Field MethodologyPositron’sInsulatorTesterallowsforthediagnosticevaluationofbothPorcelainandCompositeinsulators.

• The Insulator Tester measures the AC electric field surroundingporcelainandcompositeinsulators

• Thefieldisproportionaltothevoltageacrossaninsulatoranddropsataconductivedefectlocation

Features

Lightweight and DurableThe Positron Insulator Testers are lightweight,durableandengineeredtowithstandfieldconditions.Theycomesecureinaruggedizedcarryingcaseforconvenientportabilityandfielddurability.

Optional Data Logger (Mini Laptop)The data logger is used to identify each insulatorstring to be tested, eliminating the need to takeon-sitehandwrittennoteswhile testing.The loggerstores the identification of each insulator stringtested.
