Doble-Megger brings together Doble diagnostic systems and Megger electrical test instruments. Select equipment around the asset, test method and maintenance task, from transformer and breaker tests to cable, insulation, battery and earth measurements.
Explore the equipment and capabilities in our established portfolio. Model configuration and support can be discussed for your application.
The range covers power and instrument transformers, circuit breakers, insulation, ground systems, batteries and low-resistance measurements. Test scope and connection arrangements depend on the asset.
The CBA 3000 combines timing, travel and speed analysis with contact-resistance and coil-current measurements. First-trip testing and stored results support investigation of operating mechanisms.
