High-voltage tester POSITRON®

electrical insulationpowersafety

The POSITRON® insulator tester for high-voltage lines can be used to test many high-voltage insulators in electrical substations: power transformers, bushings, current transformers, circuit breakers, disconnectors, voltage transformers, bushings, etc. made of glass, porcelain, or composite. 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, isolators, 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 SUBSTATION testers operate at all voltage levels and for all types of glass, porcelain, or composite insulators. They are ideal for lower voltage applications (<115 kV), such as tapered insulators, bushings, barrel insulators, surge arresters, etc.
