8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

Understanding Capacitive Voltage Sensors | Fluke
The capacitive voltage sensor works because when you hold the barrel in your hand and place the tip near a live conductor, you are inserting the high impedance sensing element into a capacitively coupled series circuit. As your hand and body form a relatively large capacitor coupled to the floor. The sensor tip is a small capacitor coupled to the live …
New Standard IEC 62271-213:2021
Voltage presence indicating systems are devices used to provide information to operators about the voltage condition of the main circuit of the switchgear in which they are installed. The indication of VPIS alone is not sufficient to prove that the system is dead: if operating procedures make it mandatory, relevant voltage detectors according to IEC 61243-1, IEC …

Indicating the charge level on a capacitor with an LED
The way you make sure a high voltage capacitor is completely safe before working on it is to have a wire connecting both terminals together. Clip a wire onto both terminals. Use a conventional multimeter, with a HV probe if necessary, to see whether it''s safe to attach the wire.
