What is the formula of voltage regulation?

What is the formula of voltage regulation?

Voltage regulators are devices that are used to keep the voltage constant under varying load conditions. Load regulation (percent) = 100 x (voltage no load — voltage full load) divided by voltage full load. Line regulation is another measure of voltage regulation.

What is voltage regulation in Rectifier?

A voltage regulator is connected to the output of a filtered rectifier and maintains a constant output voltage (or current) despite changes in the input, the load current, or the temperature.

Why do we calculate voltage regulation?

Voltage regulation is the measure of how well a power transformer can maintain constant secondary voltage given a constant primary voltage and wide variance in load current. The lower the percentage (closer to zero), the more stable the secondary voltage and the better the regulation it will provide.

How is regulation calculated?

Voltage Regulation for 11KV, 22KV, 33KV Overhead Line

  1. % Voltage Regulation = (1.06 x P x L x PF) / (LDF x RC x DF)
  2. RC = (KV x KV x 10) / ( RCosΦ + XSinΦ)
  3. Required size of Capacitor (Kvar) = KVA1 (Sin ø1 – [Cos ø1 / Cos ø2] x Sin ø2)
  4. L = [1 – (KVARC / 2 KVARL) x (2n – 1)]
  5. % Voltage Rise = (KVAR(Cap) x Lx X) / 10 x Vx2.

What is voltage regulation factor?

The voltage regulation of the transformer is the percentage change in the output voltage from no-load to full-load. And since power factor is a determining factor in the secondary voltage, power factor influences voltage regulation. This means the voltage regulation of a transformer is a dynamic, load-dependent number.

What is regulation in rectifier circuit?

The term ‘regulation’ (at stated load or current) is defined as the difference between no load output and the output at stated load, expressed as a % of the no load figure. Regulation % = 100(Vo – Vl) / Vo. % ripple is another important term and is a measure of the smoothing or filtering of the DC supply.

Which voltage regulation is best?

The ideal voltage regulation should be zero.

  • Zero voltage regulation indicates that there is no difference between its no-load and its full-load voltage.
  • This is not practically possible and is only valid theoretically for ideal devices.
  • How do you calculate 11kV?

    Take a 11kV/415v, 500KVA distribution system. Then maximum current on HV side = 500/{sqrt(3) * 11} = 26.24 A. maximum current on LV side = 500/{sqrt(3) * 0.415} = 695.6 A.

    What voltage is 11kV?
