SONEL Demonstration Board DB-1

The DB-1 demonstration board is an indispensable element of training courses regarding realisation of electric measurements. It may be applied in schools, distribution centres of meters used in the power industry as well as in training centres.
The board may be used for the purpose of simulation of the following measurements:

measurement of the short circuit loop impedance in the L-N circuit for the TT and TN networks
measurement of the short circuit loop impedance in the L-PE circuit for the TT and TN networks
measurement of the parameters of the RCD switch type AC
insulation resistance measurement in the L-N circuit
insulation resistance measurement in the L-PE circuit
measurement of the earth resistance by means of the technical method
earth resistance measurement using clamps
earth resistance measurement by means of the two-clamp method
earth resistance measurements by means of the impulse method
earth resistance measurements using meters for short-circuit loop measurements
resistivity measurements of three kinds of ground
measurement of the resistance of equipotential bondings
measurement of alternating voltage

The demonstration board makes it possible to cause irregularities in the installation under scrutiny. This is possible thanks to the panel switches.
