While capable of delivering 900 A continuously and 5,000 A for short periods, the new Ingvar primary current injection test set from Megger is readily portable, making it suitable for on-site use, ...

John Hansen, Managing Director/CEO of Ether NDE Ltd, talks to AZoM about Eddy Current Testing. What is an Eddy Current NDT? Eddy Current Testing is one of the many Non-destructive Testing (NDT) ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Some of the most challenging leakage-current-testing requirements are those for patient-monitoring devices—both invasive and noninvasive. Such testing can be time-consuming and expensive, so it is ...

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

Along with the development of new instrumentation, the test procedure itself was also standardized. By “walking” the potential probe toward the current probe and graphing the measurements, the ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Figure 1. Use the circuit in (a) to measure input bias current on the op amp’s noninverting input. Adding a loop amplifier in (b) keeps the op-amp stable for measurements on the inverting input. The ...

In a perfect world, electrical insulation would allow no current to flow through it. Unfortunately, several factors can — and will — result in the deterioration and ultimate failure of electrical ...
