How to make a high voltage DC voltmeter (1000V+ !!!)

Like the high voltage AC meter, we can use the same Op-Amp circuit to measure high voltage DC voltmeter. In this article, we are going to learn how to make a high voltage DC voltmeter using a micro-controller and Op-Amp circuitry. How to sense high voltage floating DC with Op-Amp? Read more…

How to measure floating high voltage AC with Op-Amp

Measuring high voltage AC is not safe just with a resistor voltage divider. Or sometimes, we can not connect one terminal to the GND of the measuring circuit. Sometimes, we need to measure a floating high voltage. In this article, we are going to learn how to do that floating Read more…
