Note
Note:
1. If the current of the fundamental oscillation represents the main portion of the total
current (fundamental oscillation + harmonic), the wire cross section of the N-conductor
should be 3 times larger than the phase conductor cross section.
2. The CT ratio should be selected to be 1.5 to 4 times that of the maximum load current.
3. The rated current of the circuit breaker should be selected to be 1.2 times the rated
capacity of the SVG, or more.
