Features

Capacity Determination of the equipment:

1. 220kV/400mm²cable, 1km, capacitance≤0.125uF, test frequency 30-300Hz, test voltage 218kV.

Test current I=2πfCU_test=2π×38×0.125×10^-6×218×10³=6.5A（f=35Hz）

4pcs reactors will be designed, two reactors in series then two in paralleled, the output: 220KV/7A.

2. 220kV/120MVA transformer, capacitance≤0.03uF, test frequency 30-300Hz, test voltage≤335kV

Test current I=2πfCU_test=2π×45×0.03×10^-6×335×10³=2.8A（f=45Hz）

4pcs reactors are in series, each reactor is 440kV/3.5A.

3. 220kV GIS, switchgear, CT/PT, capacitance≤0.025uF，test frequency 30-300Hz, test voltage≤385kV

Test current I=2πfCU_Test=2π×45×0.025×10^-6×385×10³=2.7A（f=45Hz）

4pcs reactors are in series, each reactor is 440kV/3.5A.
