Description

SONEL DB-1 DEMONSTRATION BOARD

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 DB-1 simulates home distribution network. It enables to demonstrate the method of carrying out the following tests:

  • short-circuit loop impedance for the evaluation of automatic supply disconnection.
  • RCD disconnection time and current,
  • earthing resistance,
  • earth resistivity,
  • continuity of equipotential bondings,
  • insulation resistance,
  • mains power voltage.

N.B- It is possible to simulate typical faults and irregularities in the power network.
