In the electrical trade, there is no such thing as "medium" voltage. Line voltage is broken down into "low" and "high". Low line voltage is 220/110 volt power. In a single phase supply the only required colors are white or grey for the neutral or grounded conductor and green or bare copper for the earth ground, or grounding conductor.
In three phase power supplies, low line voltage (220/110) is marked : Phase A -black, Phase B - red, Phase C - blue.
In three phase high line voltage (480/277) conductors are marked : A -brown, B - orange
C - yellow. Neutrals are still marked white or grey. White is normally used for low voltage neutrals and grey for high voltage neutrals.
In the trade, "low voltage" is considered circuits below 50 volt, such as 12 and 24 volt control circuits, fire alarm, etc.

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...
In a color television set using a picture tube a high voltage is used to accelerate electron beams to light the screen That voltage is about?
25 thousand volts
How do you measure the current and voltage in high tension line?
To measure high voltage use suitable instrument transformer (potential transformer) Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.
What voltage is used for control circuits?
voltage
What are voltage dividers?
Voltage dividers are used in a linear circuit to separate the input voltage into a small portion known as the output voltage. It is commonly used to get a low voltage signal equal to the voltage being measured.
What is pilc cable?
Paper Insulated Lead Sheathed Cable. Used for medium voltage levels.
What is medium oak color?
Oak is not really a color but can be used to describe the color light brown as it relates to the color of an oak piece of wood.
Can you mix ash brown and medium brown hair color together?
Yes, it's OK to mix ash brown and medium brown hair color together. The ash will help neutralize the reddish tone that would normally appear if the medium brown color was used alone.
What colour to put over the medium orange to get medium golden brown and not a redish brown?
With the target color being medium golden brown and the starting point is a medium orange, I would go with a medium ash color + 20 volume developer. If you used a medium gold or a neutral, these colors would add too much brass to that already brassy orange. After using an ash color, the hair may seem a little dark at first. Once it's washed a few times, it should be at about the target color.

When refering the medium have been used in the artwork which one is correct The medium i used is or the medium i used was?
The medium I used was.
How much voltage is used per day?
Voltage is not "used" Voltage is constant.
What is used to measure voltage?
a voltmeter is used to measure voltage
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.
Are cross-element Yagi antennas always circularly polarized?
No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna. No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna.
