The Megger MWA330A 3-Phase TTR and Winding Resistance Tester is a combined turns-ratio, winding-resistance, and phase-deviation test set designed for fast, comprehensive transformer integrity checks. Available to rent or hire, the unit streamlines commissioning, maintenance, and fault-finding for utility, industrial, and service-company professionals who need reliable on-site transformer diagnostics.
Using a single set-up, the MWA330A performs simultaneous three-phase tests, automatically captures ratio, resistance, and phase information, and displays results on an intuitive colour touchscreen. Built-in demagnetisation helps prevent inrush issues after testing, while a rugged enclosure and IEC 61010 CAT IV 600 V safety rating support demanding field environments. With data storage, USB export, and PowerDB software compatibility, the tester integrates easily into existing asset-management workflows.
Key Features:
- Combined TTR & Resistance Testing: Performs ratio, winding resistance, and phase-angle measurements from a single connection, saving time on every transformer.
- Simultaneous 3-Phase Measurement: Tests all three phases at once to minimise tap-changer wear and reduce test durations.
- Automatic Demagnetisation: Integrated routine demagnetises the core after resistance testing, helping eliminate energisation problems when the unit is returned to service.
- Colour Touch Interface: Large display with straightforward menus simplifies test configuration and makes on-site analysis easy.
- Data Storage & Reporting: On-board memory, USB export, and PowerDB compatibility facilitate secure record keeping and trend analysis.
