產品總覽

The Megger MWA300 and 330A Transformer Winding Analyzers are here to offer you 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 MWA330A comes equipped with a built-in computer that has a 305 mm (12 in) color display and touch-screen interface. The computer is designed to control the unit and it can store up to 100, 000 data sets.

Key Features

Combines TTR and resistance testing in one box - faster, more efficient testing

55% smaller, 40% lighter than individual instruments

Only one set of leads required - lighter, smaller and less expensive

One test form - easier, faster to complete

Built-in demagnetization

Benefits

The following tests are easily performed with a single instrument

3-phase turns ratio

3-phase winding resistance

OLTC continuity (make-before-break)

3 phase core demagnetization

Magnetic balance / flux distribution

Excitation current

Polarity and phase angle deviation

Auto vector detection

Heat-run test
