What does a capacitor look like?
The physical appearance varies depending on the type of capacitor in question. The main similarity between the different types is that they have two leads.Electrolytic Aluminum Capacitors come as metal cans in appearance, and can be radial (both leads at the bottom) or axial (one lead at the top, one lead at the bottom). This type of capacitor is also polarized and typically will have a symbol indicating which lead should be connected to ground (most common) or a symbol for the lead that connects to the voltage source. Typically there will be a capacitance rating in Farads on the capacitor.Ceramic Capacitors come in many different appearances, one commonly found is a disc shape. These capacitors are not polarity sensitive and thus have no markings indicating polarity. They are smaller than Electrolytic Capacitors and usually do not have enough space to display a Farad rating but will use a numeric code (similar to color bands on resistors)There are many other types of capacitors and also "homebrew" capacitors composed of soda bottles and tin foil, which makes giving an exact answer to "What does a capacitor look like?" difficult.
What is the difference between directional and non directional over current protection?
The directional part. Directional relays will operate for events "in front of" them, but will not operate for events "behind" them. Typically directional relays are used in non radial situations such as on the bulk electric system. Non-directional overcurrents are commonly used on radial lines.
What is capacitor LS?
The distance between the leads (lead spacing) on a radial capacitor
What is the difference between a ring circuit and a radial circuit?
It as simple as the name implies ring circuit ,it 's in the circular form that is from the panel to the outlet and back to the panel . While radial is from the panel and stop at the out let without going back to the panel.But note that in a ring circuit you must use 6mm cable and 32/30 amp fuse rated.AnswerRing-main circuits must be wired using 2.5-mm2 cables, not 6-mm (whatever that is) cables.
What is meant by radial feeder?
In a power system, a "radial feed" is one where a source is only present at one end of the transmission line. If a source of power is present at both ends, it is said to be a networked line.
