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.
