About Photovoltaic Energy StorageFor example, ABB Transmit Oy have designed a relay that measures the current in the capacitor bank and transforms this into a voltage that corresponds to the voltage across the elements in the capacitor bank. This relay is called SPAJ 160C and includes unbalance protection, overload protection and undercurrent relay. ...
About Photovoltaic Energy StorageIn a generated 230 or 460 VAC 3 phase system, you should always measure about the same 230 or 460 volts between any two legs, (unless your supply power factor is way off). All of this applies here in the US. Three-phase in Canada, and much of the rest of the world, operates the same but at lower voltages (190 / 380) and at 50 Hz …
