The RC Delay Element

The RC delay element is a way to create a time delay in your circuit by connecting a resistor and a capacitor. It''s super simple. And very useful. The ''R'' is a resistor, and the ''C'' is a capacitor. That''s where the ''RC'' comes from. And here''s how you connect the two:

Can a capacitor be used for overvoltage protection?

Relying on a capacitor to fail in an overvoltage condition in order to protect some other equipment is a bad design practice. Capacitors may fail open, short, or somewhere in between; unpredictability makes for poor protection. And I''ve personally seen overvoltaged

An Incremental Quantity Based Distance Protection With Capacitor …

Series capacitors increase the power transfer limit of transmission lines. However, the protection of series compensated lines using only local measurement is challenging. Phasor based distance protection experiences delay and directional problems in the presence of a series capacitor. This paper presents an incremental quantity based …

Capacitor Selection Tips For Transient Voltage Protection

Transient voltage protection is not just something that is "nice to have," but rather it is required in many devices. Power systems, industrial systems, networking equipment, and even simpler devices with some connectors can all function without transient protection, but there is a risk that devices fail when transients occur.
