Hipotronics 2293 for Rent, Winding Resistance Meter and 3-Phase, TTR Option

Product Highlights

The 2293 is an automatic winding analyser, optimized for three phase power and distribution transformer measurements. It uniquely combines winding resistance measurement, turns ratio, dynamic resistance measurement, core demagnetisation, transformer type detection, magnetic balance, short circuit impedance and heat run test (temperature rise and cooling curve) in the fastest single instrument solution on the market. A simple "one-time-connection" system drastically reduces measuring time: once connected all tests can be performed in a row without any reconnection. The built-in simultaneous winding magnetization method guarantees fast and reliable resistance measurements. Stable measurements are reached even on large power transformers with delta windings on the low voltage side. A progressive method for measuring transformer turns ratio guarantees results closer to the nominal ratio even in large power transformers with tertiary windings.

• 3490068, 3-phase Winding Analyzer, 32A, 67V
• Multipurpose winding analyzer: transformer winding resistance, turns ratio, dynamic resistance on tap changer, type detection, arbitrary phase ratio measurement, demagnetisation, short circuit impedance, magnetic balance and heat run test (heat rise and cooling curve) in one instrument
