CombiTest 2019 makes it possible to carry out testing in the enterprises of the parameters of electrical networks according to standard VDE0413. You can write the results of testing beside the memory of instrument, transfer them for further the processing beside the computer. Using ON, you will set up the professional base of reports.

Instrument makes it possible to carry out

• Test of electrical conductivity and the measurement of the resistance of the shielding ground wires and connection to neutral
• Measurement of insulation resistance with the test stress of 50[V], 100[V], 250[V], 500[V] and 1000[V] of direct current.
• Measurement of the parameters BONDS (ACE, common and selective type a) - tripping time, the current of turning off, contact voltage, the impedance of the ground circuit
• Measurement of stress and frequency
• Determination of the alternation of the phases
• The measurement of the impedance of chain “phase- phase”, “phase is the earth” and “phase - neutral particle”, the calculation of the expected short-circuit current
• Measurement of the impedance of the tire of grounding on the 3rd to wire diagram without turning off OF BONDS and according to 4 wire diagrams (method Of [vennera])
