Where to place high voltage indoor capacitors

How do I choose a voltage for a capacitor?

In other words you generally want to pick a voltage that is substantially higher (2x) than the voltage being applied to the cap. The derating curve can be found in the data sheet of the capacitor and should be used to validate that a sufficiently high voltage was selected.

Where can a capacitor be found?

They are to be found in high voltage transmission and distribution systems, in transformer substations and also at various levels in low voltage installations. Capacitors therefore have to be made in accordance with very diverse technical specifications, for powers ranging from a few kvar to several Mvar.

How to determine capacitor size & location?

There are different methods for determining capacitor size and location. The most common method (intuitive) is based on rules of thumb followed by running multiple load flow studies for fine-tuning the size and location. This method may not yield the optimal solution and can be very time consuming and impractical for large systems.

How do you optimize a capacitor?

The most effective method is to use the Optimal Capacitor Placement (OCP) program to optimize capacitor sizes and locations with cost considerations. OCP employs a genetic algorithm, which is an optimization technique based on the theory of nature selection. OCP uses the “Present Worth Method” to do alternative comparisons.

Should a DC blocking capacitor be placed near a receiver?

There are two compelling arguments: The first argument is, put the DC blocking capacitor close to the receiver and you’ll be good, since all of the reflections will be smaller due to transmission line attenuation. This represents a time domain view of the world.

Which type of wiring is best for a capacitor?

For this reason, double star connection is preferable. Go back to Content Table ↑ This type of wiring is suitable for all powers and all voltages of capacitors. It retains the advantages of star connection, and adds a protection mode enabling internal faults to be detected.
