The coil of the grounding relay is connected to a zero-sequence current transformer (cable type, busbar type, or zero-sequence current filter composed of three-phase current transformers). When the zero point of the protected motor is grounded through impedance, the relay is connected to the differential circuit of the converter.
DetailsDistributed photovoltaic power generation specifically refers to photovoltaic power generation facilities that are built near the user's site, and whose operation mode is characterized by self-consumption on the user side, surplus electricity connected to the grid, and balanced adjustment in the power distribution system.
DetailsIn today's ever-changing energy landscape, power outages in power distribution networks can still cause disruptions to critical operations of enterprises, such as production processes, resulting in huge losses.
DetailsElectric shocks can cause a lot of injury, especially when maintaining and repairing power lines and pylons. It is difficult to isolate and check for voltage in a wire without cutting it.
DetailsSolar photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Regardless of whether it is used independently or connected to the grid, the solar photovoltaic power generation system is mainly composed of three parts: solar panels (components), controllers and inverters.
