The technical solution relates to device for automatic measuring the connection of the protective conductor (PEN) and (PE). Described technical solution consists of two devices. The first device (PENCE) is designed for automatic detection of connection of the protective conductor (PEN), namely from the source, i. e. from transformer to the distribution point (PEN) of the conductor by the measuring current transformer (MTP). Second additional device (ENCE) automatically detects connection of the protective conductor (PE) from the point of sharing the conductor (PEN) in distributor to the end appliance in the electrical installation, in network (TNC-S). The current use of the device (PENCE) and (ENCE) covers the control of the connection of the protective conductor from the power source, i. e. from the transformer to the appliance. |
