The Current Transformer, also known as the Current Transformer, is an essential device for the correct functioning of a photovoltaic system, since it is used to protect and measure the alternating current of the electrical circuit up to 200A.
The V-TAC SKU 11506 is a Toroidal Current Transformer designed with an isolation of the current sensing circuit from the power circuit. This prevents short circuits and ensures operator safety.
The ring of the toroidal CT is positioned on the phase (L) of the circuit, connected between the inverter (master) and the network (grid), to detect the alternating current produced by the photovoltaic system. In a three-phase electrical system, 3 CTs will be needed, one for each phase.
The signal produced by the toroid is transmitted via 2 signal cables, connected to the photovoltaic inverter in the designated inputs according to the instructions in the manual. This signal is used by the inverter to control the production of electricity. The CT is highly accurate in measuring current.
In summary, the Current Transformer plays a critical role in protecting and measuring the current in a photovoltaic system, ensuring safe and efficient operation of the system.
