3.3.3.3 Voltage actual value sensing
The voltage actual values are measured using AVT combination modules, whose measuring
resistors are connected in series. This ensures a high degree of measuring accuracy.
① AVT combination modules
② Transformer
③ Measuring resistors
④ Surge suppressor (only > 3 kV)
⑤ 80 kHz power supply
