Taps on Capacitive Voltage Transformers

09/26/2017 12:03 AM

Dear Sirs,

I have read that in the capacitive voltage transformers (eg 132 kV): taps are given on primary side. What is its use?

Regards,

If you touch that side, they play taps for you!

All transformers, the taps are on the Primary side. It use to change the voltage.

Transformers have taps to change ether the input voltage or the output voltage. On the high voltage side would be for adjusting input voltage according to actual line voltage A CVT is use to attenuate transient frequencies induced on the High voltage lines to clean up the output low voltage for high speed communications installations and low voltage equipment control systems.

J.E.V

P.S Is this a test?

In electric distribution substations one will often find capacitors with multiple taps on them employed for the purpose of selecting the VARS (power factor adjustment), and thus effecting a voltage adjustment on the local grid.

A synchronous condenser (this link: motorized generator or synchronous condenser?)

Why are we not seeing more installations of these where DC grid is being converted to AC?
