The following provides details of our test capabilities used in the development process of new products, as part of a quality assurance programme or to identify failure modes in existing products. Testing is generally carried out to recognised IEC / ASTM standards although these often have to be flexed to account for the specific environment within which a device will be tested. All testing can be carried out at a range of pressures / temperatures as required.
Measuring the quality of products before high voltage test is often desirable and is done using techniques such as insulation resistance measurement and dielectric spectroscopy. In addition to the below we therefore have a range of suitable equipment at aHV and access to a wider portfolio of advanced analysis equipment (such as X-ray tomography) through the Manchester based Royce Institute.
High Voltage Test
The majority of our test equipment is Labview controlled giving us an ability to accurately rise test voltages at given ramp rates and for certain testing rely on automation to maximise the repeatability of test results.
We have the capability to thermally age samples at temperatures of up to 600oC with higher temperature capability being available on request. We can also thermally cycle samples.
