The Megger TTR330A is engineered for rapid, precise turns ratio testing of complex three-phase transformers, including units with multiple tap changers and bushing CTs. It operates between -20°C to +50°C, featuring a 12-inch sunlight-readable touch controller and built-in 2-inch printer. The device stores up to 100,000 test results and includes a safety shutdown function for data protection during power interruptions.
Designed for substation or manufacturing use, it accurately measures turns ratio and phase deviation to detect core faults and shorted turns. Results can be printed or exported to a PC for detailed analysis.
