Detailed Description

Capacity Determination of the equipment:

4pcs Reactors will be designed, each reactor is 2500 kVA/150kV. Capacity amount is 10000kVA.

Determination:

1)    When to do AC withstand voltage testing on 170kV 2000mm2 10kM power cable.

Using 4pcs reactors in paralleled.

Output 150kV/66.6A, testing current is calculated as below:

I=U×103×ω×C×10-6=66A (U:150kV,C:2uF,ω=2πf (f=35Hz))

2)    When to do AC withstand voltage testing on 400kV 2000mm2 5kM power cable,

Using 2pcs reactors in series and then these two groups in paralleled.

Output 300kV/33.3A, testing current is calculated as below:

I=U×103×ω×C×10-6=29A (U:220kV,C:0.6uF,ω=2πf (f=35Hz))

3)    When to do AC withstand voltage testing on 400kV and below voltage degree GIS and etc. equipment, the capacitance is 0.02 uF,

Using 4pcs reactors in series, output 600kVA/16.6A, resonant frequency and testing current is calculated as below:

I=U×103×ω×C×10-6=3.3A (U:512kV,C:0.02uF,ω=2πf (f=50Hz))
