Italian DOSSENA overvoltage limiter

All safety regulations require special attention to the dangers caused by accidental contact between medium and low voltage circuits. Especially the flashover from the medium voltage coil to the low voltage coil in transformers. Due to the fact that such accidents cannot be completely avoided, it is necessary to adopt appropriate methods and means to protect low-voltage lines from overvoltage.

The Italian DOSSENA overvoltage limiter (overvoltage limiter, overvoltage regulator) is mainly used to prevent fires caused by high voltage on low-voltage circuits. According to the connection level, it can be divided into four types: LT1, LT2, LT3, and LT4.
