I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

A voltage divider is a passive linear circuit used to create a voltage less than or equal to the input voltage. It is a conversion device composed of a high-voltage arm and a low-voltage arm. The ...

Many research and productionapplications require low-level voltage measurements to characterize materialsand devices. When signal voltages approach the microvolt ...

Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...

Battery cell voltage is the most fundamental measurement made on the cell. While on the surface measuring voltage seems easy, challenges and accuracy considerations must be understood before your cell ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...
