The connection takes place when the voltage network matches that of the capacitor when it is partially or totally loaded, as seen Fig.1.

電容器在半或全負載時,當它的電壓和網路電壓相當時,連接就會產 (發) 生.
"that" means "voltage".
that of the capacitor = the voltage of the capacitor

You need to know how capacitor works, then you can understand the sentence better, here is a link to explain how it works:
Basically, capacitor is a device to store energy (in voltage form).

The most common one is to use with an electrical motor. As you might know, to start a motor you need quite an amount of energy (especially, the voltage), therefore, lots of time, a motor will have a capacitor connects to it,

and let the capacitor to build up the needed voltage before send the energy to the motor to turn (or start) it.
