What is a neon transformer rated?
depending on the length of neon.. a large sign 15Kv at 60 Ma is common 1Kva
Why railway used 25 kv system?
25kV is used with 50Hz systems, and 15kV is used with 16 2/3 Hz systems. With higher frequency the power lines have higher impedance and you need higher voltage to transfer energy.
What is the capacitive voltage transformer in sub station?
A coupling capacitor voltage transformer (CCVT) is composed of two stacks of capacitors which step the primary voltage down to a lower voltage potential transformer. These are typically used on 100kV and above, and the potential transformer is often around 15kV on the primary side. There are two reasons to use CCVTs over PTs (potential transformers) - at the above voltage levels, they are cheaper, and they can be used for power line carrier signal injection. Under transient conditions, CCVTs typically won't perform as well as PTs, and also may have worse accuracy ratings, so are often not acceptable for metering purposes.

What is the rating of the protective covers that you must install on all of the unused high voltage bushing wells of the secondary distribution center?
15Kv
What is rmu type vrn2a?
"RMU Type VRN2a" is a Lucy Switchgear 12kv(15kv) Sabre type, Ring Main Unit
What is the rating of protective covers that you must install on all of the unused high voltage bushing wells of the secondary distribution center?
15Kv
What would be the rating of gronding transformer for 3150kva stra delta primary stra3311kv trasformer?
It has the highest voltage rating to bring it to the primary supply. This supply is at 17.5kV for 15kV, 24kV for 20kV.

Tesla coil with a NST that's 15kV rated at 30 mA which mains outlet should you use?
For those building their first coil, I would not suggest using this a standalone source of instructions. If you got those specifications, you should know the answer. Otherwise is not wise to build it alone.
How can you step down a 15kv transformer single phase to 220v?
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
What is unit transformer?
UniT transformer are step up transformer which is connected to generating house & step up voltage from 11/15kV votlage to 220/400kV voltage level as requirement or line design parameter. It is just like transformer but connected to unit of the generating house that's why we called it unit transformers.
How to step down 15kiloV to 20V for practical purposes?
Stepping down AC voltage is accomplished using a transformer. In your case the primary (15kV) to secondary (20v) ratio is 750, which is very high for a typical transformer, so I suspect you would need to step down to some intermediate voltage, and then use a second transformer to step down to 20 volts.
What is the function of TV flyback?
The TV flyback transformer is obsolete in modern television sets and is not used.In the old cathode ray tube (CRT) television sets the flyback transformer had two functions:generate a large and powerful current pulse to drive the horizontal deflection coil in the yoke around the neck of the tube to create a quick horizontal retrace between sweep linesusing a large secondary autotransformer winding produce a very high voltage (i.e. 15KV to 100KV) rectified by a high voltage diode needed by the anode of the CRT to accelerate the electron beam
