UHF PD Detector
-
Handheld online PD substation surveying system. The UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of the toolkit for all maintenance and service teams. Due to its high measurement bandwidth, the UHF method provides accurate local online partial discharge (PD) measurements on HV components such as cable end-terminations, surge arrestors, voltage transformers and isolators.

Cable Diagnostic Tools
-
For non-destructive diagnostic testing to determine the quality of a cable’s insulation with minimal risk of failure, HVI recommends tan delta and partial discharge testing for valuable diagnostic data about cable insulation integrity. Both use a VLF source to perform elevated voltage, off-line testing. Tan delta testing measures insulation health, while PD identifies specific problem areas and assesses their severity.

C Series Digitizer Module
Digitizer
The C Series Digitizer Module takes both high-speed and high-resolution time- and frequency-domain measurements. It features up to four channels that can sample at speeds up to 20 MS/s—ideal for discrete detection of signals 10 MHz and smaller for applications such as fault detection, partial discharge analysis, and acoustic measurements. The module's store-and-forward architecture allows up to 128 Mbits of measurement data to be sent back to the CompactRIO Controller and analyzed. You can use the module as part of a CompactRIO system and use the LabVIEW FPGA Module to develop an advanced trigger based on low-speed streaming for added flexibility. This digitizer includes the NI-DAQmx driver and configuration utility that simplifies configuration and measurements. NI-DAQmx supports NI programming environments and Python, ANSI C, C#.NET, and MathWorks MATLAB® software.

Qualification and Quality Control Tests
Techsquare
-
New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

Electrostatic Discharge Test
-
The electrostatic discharge test is designed to determine the ability of equipment to perform its intended function without permanent degradation of performance as a result of an air discharged electrostatic pulse. Electrostatic discharge is the result of an unbalanced electrical charge. Typically, it is created by insulator surfaces rubbing together or pulling apart. A transfer of electrostatic charge between bodies (materials, components, etc.) at different electrostatic potentials is caused by direct contact.
