The DB-1 demonstration board is an indispensable element of training courses regarding realization of electric measurements. It may be applied in schools, distribution centers of meters used in the power industry as well as in training centers.

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.

Product Details:

The SRP-50k0 - 5T0 calibrator is a source of high resistance, used as a standard in calibration and tests of analogue and digital insulation resistance meters.

The setted resistance by the calibrator can be maintained for a long time under external direct voltage up to 5000 V, provided that the current in the measuring circuit does not exceed 3 mA.

The required resistance is set by the user using the calibrator's touch keypad or via an external PC application. The required value is set automatically thanks to the switching of a precise resistance matrix. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.

Calibration box CS-5 kV, due to high-quality resistors, with very high accuracy class, perfectly suited to verify the indications of insulation resistance meter and is very good tool for training purposes. CS-5 kV may be used as a simulator of the insulation resistance of wires, cables or isolators. The device uses banana sockets with a diameter of 4 mm, which allows to perform in easy way the measurements of resistance using meters from Sonel's offer. In case of measuement using MIC famly meters with measurement voltage higher than 2.5 kV, to connect meter to Calibration box please use the crocodile clips and metal pins that are supplied with device.

 

Product Details:

This accessory is designed for training and presentation purposes and for providing rough estimates of resistance measurement accuracy. The results obtained from the measurements with the simulator shall be treated as estimated values, and not as calibration results. CS-1 cable simulator is designed to simulate the insulation resistance of power cables. The adapter is equipped with banana sockets with a diameter of 4 mm. This allows user to perform resistance measurements with majority of meters designed for this purpose and offered by Sonel SA. The user of the cable simulator is able to check the correctness of measuring results provided by devices of MIC series (insulation resistance meters). Other devices compatible with CS-1 include multifunctional electrical installation meters, with the function of insulation resistance measurement. Please note that the results presented in the display of the meters are approximate, and that presented value is within the basic error range of the meter itself and the cable simulator. The resistance value provided by the simulator may for a long time remain under constant external voltage, up to 1000 V. The housing is highly resistant to mechanical damage. The device allows user to perform a simulation of measurements for four resistance values.
