Safety tester POSITRON®

high-voltageelectrical insulationfor composites

The POSITRON® high-voltage insulator tester can be used to test a large number of composite high-voltage insulators on power lines, electricity pylons and transmission and distribution poles. Description Breakdowns due to insulator failure are costly. In addition, live working requires insulators to be in good condition for the safety of line workers and high-voltage workers. A critical failure can cause long-term damage as well as material and financial losses. Pollution, salt spray, dust, wear, shocks or micro-defects can dramatically alter insulator quality. Whether made of porcelain, glass or composite (silicone), the quality of an insulator is a determining factor in the robustness of your electrical installation. In a high-voltage electrical substation, many items of equipment contain insulators, such as switchgear, measuring equipment and electrical connections: power transformers, bushings, circuit breakers, disconnectors, current transformers, voltage transformers, bushings, etc. POSITRON Insulator Testers are revolutionary, lightweight, easy-to-use tools that record faults and hazardous conditions on suspended insulators, sub-station circuit breakers, bushings and live surge arresters. POSITRON insulator testers represent a major advance in insulator maintenance. POSITRON COMPOSITE testers are the only devices capable of detecting faults on composite or silicone insulators. Description of POSITRON COMPOSITE: The instrument detects obvious defects or enables early detection Records faults, up to 15,000 readings. Operates on undervoltage insulators from 69 kV to 1,000 kV. Available in 50 Hz or 60 Hz versions.
