Functions & Features of Advanced Hipot Testers – as published in Test & Measurement Tips – 6/18
Functions and Features of Advanced Hipot Testers June 18, 2018 by Lee Teschler Modern instruments help to check whether manufactured equipment meets the proliferating variety of international safety standards that govern factors such as grounding and the ability to withstand overvoltages. KEVIN CLARK, VITREK Electrical safety testers — often referred to as hipot testers — are an integral part of electrical and electronic equipment manufacturing. Hipot testers get thei name from the high-potential (high voltage) they produce to perform dielectric withstand and insulation resistance tests. In addition to these tests, many hipot testers provide accurate low-resistance measurements and low-resistance/high current [...]

Picking the Right Hipot Tester For The Job – as published in Power Systems Design Magazine – 9/2018
Picking the Right Hipot Tester for the Job Understanding the testing requirements and standards will ultimately save testing time and cost. By Kevin Clark, CEO, Vitrek Hipot testers offer a range of capabilities starting with dielectric withstand and insulation resistance testing but also, in many instances, providing accurate low-resistance measurements and low-resistance/high-current outputs to test ground resistance and ground bond integrity. Selecting the right one for your application will ultimately save both time and expense in performing these essential tests. Product Safety Certification Before getting into the individual functions, it is important to point out that hipot testing is [...]
Fiber Optic Sensor Principles
The Fotonic Sensor™ is a non-contact instrument, which uses the fiber optics lever principle to perform displacement measurement, vibration analysis and surface-condition measurements. The Fotonic Sensor transmits a beam of light through a flexible fiber-optic probe, receives light reflected from a target surface, and converts this light into an electrical signal proportional to the distance between the probe tip and the target being measured. A simplified example of the fiber optic principal is shown in Figure 2. The output signal voltage from the fiber optic sensor is then used to determine position, displacement, vibration amplitude, frequency and waveshape of a [...]
