Kalkulating Short- circuit Eduts

The basic formula for kalkulatring the initil short-circuit page (Isc) at transformer terminals is:

111; WHI1; FLT: 0 AF3; Isc = V / Z 1f; FLT: 1 123; 123;

Dimana:

  • S01; WAL1; FLT: 0 THE 3; V Systems voltale; FLT: 1: 1 After3; IS THE Systemm voltale.
  • Pertama; FLT: 0 = 33; Z = 1f; FLT: 1 = 33; INI THE TATE Impedance of the transformer and connected Systems.

Ini adalah impedance (Z) termasuk bahwa ini adalah transformer 's reactance and resistance, wwhich cun be obtained from the transformer' s impedance pertigpe and rate power.

Factors Affecting Short- circuit Edutts

Factors Severhal influence the bitcuitude of short-circuit page s in transformers:

  • Pertama, FLT: 0 = 33; Transformer impedance = = FLT = 1 = 3;: Hightur impedance mengurangi arus pendek sirkuit.
  • Pertama, FLT: 0-33; System voltale 1f; FLT: 1 1f 3; 1f voltape meningkat menjadi pendek potential.
  • Pertama; FLT: 0 = 33; Fault location = = FLT = 1 = FLT =: FLT = 0 = 0 = @ transformer result is is higher # s.
  • 111; FLT: 0 = 03; Syari3; Connected benci; FILT: 1 ASA3;: The presence of other loaden can affect systemm impedance.
