Deep dive as to why the TORKEL 950 is a flagship product:
The Megger Torkel 950 is designed for organisations where battery failure is simply not an option. In power utilities and transmission substations, the Megger Torkel 950 provides the capability to test high voltage battery banks up to 500 V and 220 A under realistic load conditions. This verifies duty cycles for switchgear, protection relays and black start systems without taking critical circuits offline. The ability to conduct in service tests reduces outage time, simplifies work permits and lowers operational risk.
Data centres and financial services rely on the testers like the Megger Torkel 950 for its dynamic discharge technology, which maintains constant current, power or resistance even as battery voltage declines. This ensures repeatable capacity curves, allowing teams to prove UPS autonomy, identify weak strings, and shift from time based to condition based maintenance. Integrated BVM cell monitoring enables early detection of cell issues, improving resilience and reducing unnecessary full bank replacements.
In transport and infrastructure areas like rail, airports, and tunnels, the Megger Torkel 950 can handle loads up to 15 kW. This shortens testing times on long strings, frees engineering resources, and enables work within limited access windows. Safety features such as airflow blockage detection, emergency stop and automatic overload protection allow safer operation in confined or hazardous environments.
Process industries and oil and gas facilities value the robust construction and traceable reporting of the Megger Torkel 950. Test results are stored on local devices.
They can be easily transferred using USB or Ethernet. This helps create reports that are ready for audits and meet compliance and reliability standards. In renewable energy sites and microgrids, the Megger Torkel 950 validates energy storage performance against actual duty cycles, supporting contractual guarantees and ensuring stable system operation.
Across all these sectors, the Megger Torkel 950 transforms battery maintenance into a proven engineering process, delivering accurate capacity verification, detailed cell analysis and dependable results that protect critical services.
