The Demonstration Board (model: DB-1), manufactured by Sonel®, is an essential component of training course concerning realization of electric measurements. In addition, this demonstration board is typically applied in schools, distribution centers of power industry meters and lastly, in training centers.
This board may also be employed in the simulation of the measurement of the short circuit loop impedance in the L-PE circuit for the TT / TN networks. In addition, it can also be used in measuring the parameters of the RCD-switch type AC as well as in measuring earth resistance through technical methods involving clamps, two-clamp methods, and short circuit measurements. The insulation resistance measurement of the L-N circuit/L-PE circuit is also possible through this device.
The demonstration board makes it possible to cause irregularities in the installation under scrutiny
