  • VLF Receiver

    T-Vlf - IRIS Instruments

    The VLF receiver is specially designed for high productivity surveys, in ground water and mining exploration. No orientation of the operator with respect to the direction of the transmitter is required since three magnetic sensors measure the components of the VLF field. Tilt or horizontality of the sensor unit is neither required since two inclinometers correct for tilted position.

  • VLF Electromagnetics

    GEM Advanced Magnetometers

    VLF surveying relies on radio signals that are broadcast from navigation stations around the world. The principle is that these signals are deflected in certain ways when they pass through conductive ore or water-filled vertical-to-sub-vertial fractures in the earth. By monitoring these deflections, the position and, potentially, size of the target can be determined.

  • VLF Insulation Testing

    Megger Group Ltd.

    VLF testing uses very low frequencies as part of an AC cable maintenance routine. VLF testers are smaller and more practical than AC testers but output the same amount of power as a 50 Hz mains device. This combination of size and power makes Very Low Frequency cable testing perfect for testing longer sections of cable and apparatus

  • VLF Voltage Generators

    Fivestar HV Testing Equipment Co., Ltd.

    VLF hipot is an AC output tester with an output frequency of 0.1 Hz or lower rather than 50/60 Hz. Although the frequency is very low, it is an alternating current with polarity reversals every half cycle.

  • VLF Diagnostics System

    PHG 80 TD - BAUR Prüf- und Messtechnik GmbH

    Cable testing and diagnostics with the BAUR PHG 80 TD. The combination of the PHG 80 programmable test generator with the BAUR dissipation factor measurement system produces the cable testing and diagnostics system PHG TD. It is operated via PC control. Dissipation factor measurement and diagnostic testing sequences can be programmed in the menu, after which the dissipation factor measured values are automatically determined in various voltage steps and a final evaluation is conducted.* Biggest dynamic range of tan delta measured values from 1 to 10-4 with a cable capacitance >10 nF to 20 uF* High resolution +/- 1x10-5 applicable even in new PE/XLPE cables* Insensitive against interferences due to complete mains separation* Lowest time required for assessing a medium-voltage cable (3-phase approx. 1 hour)
