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...
What else can I help you with?
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.
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.
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 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 medium voltage of circuit breaker?

What is the definition of a dimmer switch?
A switch that regulates voltage to something.
What quantity does the voltmeter measure when the switch is open?
When the switch is open, the voltmeter measures the potential difference or voltage across the two points connected by the switch, as no current flows through the circuit. This measured voltage is often referred to as the open-circuit voltage.
Describe the difference between a sourcing input and a sinking input?
An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->load->ground. A sinking circuit would be drawn as Voltage->load->switch->ground. In these cases, the switch could be a transistor.
