DB-1 Demonstration Board WMPLDB1

A table that allows for the simulation of electrical measurements, faults, and irregularities in circuits. It allows for the presentation of measurements of fault loop impedance, RCD parameters, insulation resistance, and continuity of protective and equipotential bonding connections. A unique feature is the ability to present grounding measurements using technical methods (3P, 4P), the technical clamp method, the two-clamp method, and also using a fault loop measuring device.

For each measurement, various operating conditions can be simulated and typical errors and irregularities occurring in real-world installations can be shown. The design of the DB-1 allows it to be used anywhere provided it is powered by 230 V. All measurements performed using the DB-1 do not interfere in any way with the installation to which the demonstration board will be connected.
