Designed for precision and power, the Megger ODEN AT Primary Current Injection Test System excels in testing protective relays, circuit breakers, and current transformers in high-voltage substations. With configurations delivering up to 21 kA (ODEN AT/3H), its modular setup—featuring S (standard), X (30/60 V output), or H (high-current) units—adapts to diverse needs. The system measures critical parameters like turns ratio, impedance, and power factor, displaying results on a multilingual LCD.
Its I/30 function presets low current to prevent overheating or unintended trips, ensuring accurate results. Dual channels allow simultaneous primary and secondary measurements, enhancing efficiency, while a USB port enables seamless data transfer. Portable via a compact cart, units weigh 25 kg (control) to 108 kg (H unit), operating reliably from 0°C to 50°C. Safety features, including thermal cut-outs and circuit breakers, protect users and equipment. With applications like heat runs, polarity tests, and ground grid verification, the ODEN AT is a vital tool for engineers commissioning switchgear and ensuring the reliability of critical power infrastructure.
