IVT1000 SERIES

3-Phase power supplies with variable frequency
For induced AC voltage tests

Output frequency 50-200Hz
Output voltage 0-1000V
For power transformers up to 2000kVA

Innovative and efficient inverter technology generates a low distortion 3-phase sinusoidal output voltage. The system features precise measurement and full protection.

Induced AC Voltage Tests - Requirements of the IEC standard

Induced AC voltage (ACSD) tests must be performed during routine and type tests at power transformers according to IEC 60076-3. A symmetrical sinusoidal 3-phase power supply with at least twice the nominal frequency is required for these tests. The test voltage is normally set to twice the nominal voltage.

The IVT1000 series meets exactly these requirements.
