Ct Vt Ratios: VT_STANDARD
Standard current transformer (CT) and voltage transformer (VT) ratios, accuracy classes, burdens, and ratings per IEEE C57.13. Covers metering CTs (0.3 class), relaying CTs (C100–C800), and standard VT ratios.
| instrument transformer type | ratio designation | accuracy class | notes | ratio value (dimensionless) | standard burden VA (VA) |
|---|---|---|---|---|---|
| VT_STANDARD | 115KV:120V | 0.3 | 115000/120 | 958.3 | 400 |
| VT_STANDARD | 138KV:120V | 0.3 | 138000/120 | 1,150 | 400 |
