VAX-230 – High Voltage Amplifier (former IDA HVU)
The life of a piece of equipment is usually limited by the life of the electrical insulation. Therefore, knowing the status of the electrical insulating material in an installation is of utmost importance to the net management. The reasons may vary; personnel safety, increasing demand for secure power deliveries as well as economic aspects.
The VAX-230 High Voltage Amplifier is used with the IDAX system to increase the output voltage. The main application for this combination is for diagnosis of water tree deteriorated XLPE-cables. The system works equally well when other types of nonlinear materials are to be characterized. The IDAX system uses the method dielectric spectroscopy, i.e.measurements of the capacitance and loss of a material as a function of frequency. The method show significant advantages in the interpretation of the results, especially compared to simplified methods like measurement of dissipation factor, tan delta, at a fixed frequency.

There are two more version of the VAX series available:
VAX-220, 20 kV, 20 mA
VAX-214, 10 kV, 40 mA
