<p>The invention relates to a voltage measuring transformer for transforming a high voltage into a low voltage, which transformer comprises:
- an iron core;
- a primary, high voltage, coil (2) wound around the core;
- a secondary, low voltage, coil (3) wound around the core; and
means (4,5) for increasing the resistance upon the occurrence of ferro-resonance arranged in series with the primary, high voltage, coil.</p> |
