Low-voltage pulse reflection method applies to test the range of the low resistance and broken line, and the length and wave velocity of various cables. Pulse current testing method can be divided into breakthrough high-voltage flashover and DC high-voltage flashover for the high resistance and flashover cable fault finding.

  • Peak Voltage Measurement

    Mess- & Prüfsysteme GmbH

    In high voltage measurement technology, the peak value, or the effective value, of the voltage is determined in accordance with VDE 0432 or IECV 60060. The peak voltage measuring device from MPS Mess- & Prüfsysteme GmbH can measure these two values in connection with a high voltage divider (capacitive or resistive). In the event of flashovers in the high-voltage circuit, this is indicated in the SMG.

  • Acoustic Probe

    AA-Ultrasonic - IPEC Ltd.

    The AA-Ultrasonic acoustic probe is designed for use on air insulated terminations where a clear sound path between the electrically stressed insulation and the probe is present. The sensor is extremely sensitive and can detect activity below 10pC. The probe has a magnetic base to allow coupling to steel enclosures and a swivel head as so the detecting sensor can be aimed directly at the HV point. Corona in air and surface tracking can seriously damage high voltage insulating surfaces in a way that will ultimately lead to flashover and complete failure of the insulator. This discharge activity creates acoustic emission that can be detected using a high frequency sensor. The magnitude of the acoustic emission is indicative of the degree and severity of the discharge activity.

  • Arresters

    Hubbell Power Systems Inc

    Next to your people, your power grid infrastructure is your largest and most valuable investment. Protect it with Hubbell Power Systems, Inc. surge arresters. Every lightning strike, insulator flashover and switching surge adds wear and tear to your equipment, prematurely aging it, and requiring you to shoulder the costs of replacement. Even the smallest surge can shorten your equipment’s life. Surge arresters, however, extend the life of your system by limiting the voltage across your equipment during a surge event.

  • Cable Fault Locators

    Fiberinthebox

    Cable Fault Locator is a device used for short circuit faults, cable cuts, resistive faults, intermittent faults, and sheath faults. Fiberinthebox supply cable fault locator for power cable, optical fiberal cable, etc. Fault Location in Power Cable is designed to locate cable faults, pinpointing the fault location, route tracing, cable identification, voltage withstand test and cable information management. It can locate all kinds of cable faults for all voltage level cables, including open circuit, short circuit, low insulation, high insulation and flashover faults, etc. Most power cables were buried underground, invisible, and out of reach, with modern new power cable fault locater, it can find the fault point quickly, solve problems immediately and restore power supply.

  • Dielectric Breakdown Voltage and Dielectric Strength

    ASTM D149 - National Technical Systems

    This test method covers procedures for the determination of dielectric strength of solid insulating materials at commercial power frequencies, under specified conditions. Unless otherwise specified, the tests shall be made at 60 Hz. However, this test method is suitable for use at any frequency from 25 to 800 Hz. At frequencies above 800 Hz, dielectric heating is a potential problem. This test method is intended to be used in conjunction with any ASTM standard or other document that refers to this test method. References to this document need to specify the particular options to be used. It is suitable for use at various temperatures, and in any suitable gaseous or liquid surrounding medium. This test method is not intended for measuring the dielectric strength of materials that are fluid under the conditions of test. This test method is not intended for use in determining intrinsic dielectric strength, direct-voltage dielectric strength, or thermal failure under electrical stress (see Test Method ASTM D3151). This test method is most commonly used to determine the dielectric breakdown voltage through the thickness of a test specimen (puncture). It is also suitable for use to determine dielectric breakdown voltage along the interface between a solid specimen and a gaseous or liquid surrounding medium (flashover). This test method is similar to IEC Publication 243-1. All procedures in this method are included in IEC 243-1. Differences between this method and IEC 243-1 are largely editorial. Note: The above information is taken directly from the test method Scope published in ASTM D149.
