Transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using Transformer turns ratio meters correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Megger’s range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase Transformer turns ratio meters ,winding analysers and PT and CT TTR testers.
Adiradh Energy offering Megger make True 3phase transformer turns ratiometer TTRU3 and 3-Phase Ratio And Winding Resistance Analyzers MWA Series in India .
Megger TTRU3 Transformer turns ratiometer uses a revolutionary design to perform a complete series of measurements on a transformer, including 3Ø step up turns ratio testing (patent pending). 3Ø voltage output offers numerous advantages to testing with today’s busy schedules. The TTRU3 is an important tool for determining the mechanical condition of transformers. All ratio tests are performed in one instrument, with only one 3Ø lead-set connection. The TTRU3 utilizes the latest 7 in. (180 mm) color touch display, as well as an optional printer so results are never lost. This is complimented with remote control which can be operated from a PC, as well as the ability to download results to a USB memory device.
Guaranteed accuracy ±0.05% from -20°C to +50°C
3Ø test voltage – up to 250V
3Ø step up ratio (patent pending)

Adiradh energy offering Transformer Winding Analysers Megger make Models MWA300 Externally controlled and MWA 330A Built-in Computer. Transformer Winding Analysers offer a faster, more efficient testing device through combining TTR and resistance testing in a single unit.
This advanced 3-phase transformer test system provides complete ratio, phase and winding resistance measurements with only one 3-phase lead-set connection. What’s more, it offers portability, a reduced set-up time and increased job safety. Once connected, the MWA300 performs DC resistance measurements on all high- and low-side windings without reconnection. It has an 8-terminal/6-winding resistance measurement capability and doesn’t need any inter-connected boxes, allowing you to test all 6 windings without having to disconnect and reconnect leads. The MWA300 series saves you even more time by using a single software platform, PowerDB, which means you only need one set-up and one easy-to-use test form. The MWA300 series can be used effectively test power transformers, distribution transformers, CTs and VTs, and motors and generators.
The following tests are easily performed with a single instrument, the MWA300 series, and a single 3-phase lead set connection:
The MWA330A comes equipped with a built-in computer that has a 305 mm (12 in) colour display and touch-screen interface. The computer is designed to control the unit and it can store up to 100, 000 data sets.
