Product Overview

HAEFELY / HIPOTRONICS 2293 AUTOMATIC TRANSFORMER WINDING ANALYZER (Call for Availability)

The Haefely / Hipotronics 2293 Automatic Transformer Winding Analyzer uniquely combines winding resistance measurement, turns ratio measurement, core demagnetisation, transformer type detection and heat run test (cooling curve) in one extremely fast instrument. A simple one-time-connect-all system drastically reduces measureing time. Once connected all tests can be done in a row without any reconnection.

Features and Specifications of the Haefely / Hipotronics 2293 Automatic Transformer Winding Analyzer include:

Features:

• Multipurpose winding analyzer - a transformer winding resistance, turns ratio, demagnetisation, type detection and heat run test (cooling curve) in one instrument
• Setup is made easy with a simple one-time-connection system and once connnected will test all phases and windings
• Each operation on touch screen interface with full graphical test visualization
• Unique simultaneous winding magnetisation method for winding resistance measurements, equivalent to traditional equipment with up to 100 A test current
• Advanced procedure for turns ratio and phase displacement measurement
• Demagnetisation function - transformer is returned to a demagnetized status after measurement
• Tap changer control signal 
• Data transfer over USB memory-stick or LAN 
• A valuable tool for factory test, acceptance test and regular maintenance on the following applications:
• Power transformers
• Distribution transformers
• All types of HV windings
