What are the differences between high voltage switch gear and medium voltage switch gear?

a switchgear is a term used with the electric power distribution system, and is basically a large switch or set of switches used in switching very high voltages at very high currents and can occasionally have arc overs, though they are ushually supressed by a number of safety measures. medium voltage probably being under 100KV but more than 5KV, but that's just a guess as to voltage ratings...

Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.
What is the medium voltage of circuit breaker?
low is below 600V medium 600 to 2500V High above 2500V usually medium and high voltage equipment is called switchgear the current is monitored and 3 shorts within 10 minutes will open the switch overloads are usually 200% for over 20 minutes but the big stuff is programable
When measuring voltage drop across a switch what is the maximum allowable voltage drop?
The voltage drop should be as close to zero as would be readable by a typical volt meter. If it is measurable you likely have a problem with corrosion or oxidation in switch that is increasing resistance. If you can measure a voltage drop across a closed switch contact, replace the switch. Or the switch is open, try flipping the switch!
In a circuit if the switch is closed how many volts go across the switch?
For an ideal switch, there will be no voltage drop across it. In reality, there will be a very small voltage drop, and this will be dependent on how well made the switch is, and what it is made out of.
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
What is the Location of medium voltage switch gear?
A medium voltage switch gear is on the low voltage side of the transformer. This medium voltage switch is very cost efficient as well.

Which one is not correct essential future of switchgear?
The switch gears are apparatus that functions to protect and control electric gear. They also detect overload conditions. It contains circuit breakers, disconnectors or fuses. Switch gears are of three types - low voltage switch gear, medium voltage switch gear and high voltage switch gear. They provide quick operation rather than moderate operation.
Feed drops to zero volts when light switch is turned on back to 120 volts when turned off feeds fluorescent lights?
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
How do you determine if the light switch has power?
You will need a voltage tester to determine this. Put the tester across the top screw on the switch to the ground wire in the switch junction box. If there is an indication of voltage you can assume that the problem is further down the circuit. If there is no indication of voltage on the top screw then test between the bottom screw on the switch to the ground wire. Sometimes the "hot" is on the bottom screw. If there is no voltage present at the switch you have to work your way upstream towards the distribution panel to see what is interrupting the voltage.
Can the 12 GB PlayStation 3 console work on either 110V or 220V?
If there is a switch on the power supply that allows you to switch between the two voltages then the answer is yes. If there is no switch then you will need to use a travel voltage adapter to convert one voltage to the other.
What is difference between a switch and a diode?
Both have two terminals, but a switch has a mechanical actuated element that closes the circuit. A diode does not have this. A diode blocks current flow when a reverse voltage (that is not too large) is applied to it, but when a forward direction voltage is applied current is allowed to flow; the cost is a small voltage drop across the diode. A switch doesn't care which direction current is flowing, and there should not be any voltage drop (ideally) in a switch.

How a meter would be connected in a circuit to measure the voltage at a light bulb?
"Voltage" is the difference in electrical potential between two points in a circuit.If the voltage across the light bulb is what you want, then first make sure thatthe meter in your hand is a voltmeter, and then touch each probe of the voltmeterto one of the connections on each side of the light bulb.If you want to determine whether power is getting to the light bulb, you stillhave to do it by measuring the difference in voltage between two points. Youcould use your voltmeter to measure the voltage between one connection atthe bulb and one connection at the switch. If the power is getting from theswitch to the bulb, then the voltage between the switch and the bulb shouldbe zero (or very small).The voltage between the two connections to the switch should be zero whenthe switch is ON, and mains voltage (115 or 220) when the switch is OFF, etc.I have worked alongside individuals in the past who claimed that they coulddiscern the presence of voltage, and even measure it, by licking their fingerand touching it firmly to the circuit point in question. I don't know how manyof them are still alive, and I strongly recommend AGAINST that technique.
What is the meaning of in-out isolation in rf switch?
The in-out isolation is the attenuation between input and output ports of the switch when embedded in a circuit, when the switch control voltage corresponds to the "OFF" state of the output port.
What is the difference between iron clad double pole switch and double pole single throw switch?
Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
When measuring voltage drop across a switch what is the maximum allowable voltage drop?
The voltage drop should be as close to zero as would be readable by a typical volt meter. If it is measurable you likely have a problem with corrosion or oxidation in switch that is increasing resistance.
