13.1
Transfer between two sources with one outgoing load
Transfer with T1 (kVA) = T2 (kVA)
The transfer switching equipment can be used for transfer between 2 sources with equal
power (T1 (kVA) = T2 (kVA) and with an outgoing load. The 3KC8 series offers the ideal
solution both for network / network applications as well as for network / generator
applications.
