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 [...]
Vendors Support Hipot, Insulation-Resistance and Ground-Bond Tests- as seen in Rick’s Blog on the EE Website – 7/18
Vendors Support Hipot, Insulation-Resistance and Ground Bond Tests by Rick Nelson - Evaluation Engineering - July 2018 To meet the requirements of your electrical safety testing applications, you can choose from a variety of instruments and systems that perform hipot, insulation resistance (IR), ground-resistance and ground-bond (GB) tests across a range of industries. Vendors offer a variety of options — from software that automates instrument control and records test results to a variety of test probes and leads. Relevant standards range from IEC 60601-11 for medical device testing to IEEE Std 43-20132 for testing the insulation resistance of electrical machinery. [...]
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 [...]
Engine Vibration and Balancing Principles
What do you think when you’re flying home, cruising at 30,000 feet and the drinks have just been served? Our engineers think about the ripple in the glass. That ripple signals vibration and is an indication that the engine may be in need of a balance. The MTII’s PBS-4100+ Series Turbine Vibration Analyzer/Balancing System was developed to ensure that Turbine engines run as efficiently as possible. Excessive vibration is detrimental for a host of reasons: energy intended for useful output is instead expended on the vibration vibration manifests as acoustic energy (noise), again wasting otherwise useful energy excessive [...]
Laser Thickness Gauge System Principles
The Microtrak™ 3 TGS system is specifically designed for thickness applications utilizing two lasers. The product can be used in a standalone configuration or easily interfaced with PLCs and PCs. Each module contains an integral LCD display and keypad for setup and display of measurements. A USB serial port also allows control by a laptop computer. Basic PLC or control input/output is provided by discrete digital I/O lines or a Modbus® interface. Laser Triangulation Principle The Microtrak™ 3 TGS system uses the principle of laser triangulation to perform a one dimensional measurement of a target. The [...]

Perspective: The Importance of Aviation Engine Vibration Testing
A White Paper by Rick Jones, President and CEO of MTI Instruments, addressing the industry-wide challenge of aviation safety and service and the importance of jet engine testing.
Handheld Signal Source Generator Principles
The MTI 1510A Portable Signal Generator is a sophisticated two channel battery powered microprocessor controlled direct digital synthesizer. It can generate sine, square, saw tooth and triangle continuous signals on both channels as well as single pulse and odd pulses on the B channel to simulate tachometer output pulses. The main reason for two channels is to be able to create a phase shift in the A to B output signals as may be encountered in a piece of rotating equipment such as a jet engine. The A channel also has the ability to simulate precise DC signals or [...]
