Leakage current sensors for charging stations

Every household has one Most people are familiar with the residual current device (RCD) from their fuse box in the basement. Though one will find several old buildings still equipped with safety fuses and cabling without earth wire, they are becoming increasingly rare. This is fortunate, since the task of the safety fuse or the circuit breaker is limited to protecting the powerlines from overcurrent, i.e. it constitutes a fire protection measure. The RCD, on the other hand, directly protects humans against fatal electric shocks. It compares whether the amount of current flowing out of the circuit is equal to the amount that flowed in. Any deviation points out to the presence of a leakage current which...
