HYTBBM series low voltage end in situ compensation device
product description
The intelligent low-voltage line automatic reactive power compensation device is designed according to the nature of the load, which can increase the system power factor from about 0.65 to above 0.9, increase the transmission capacity of transformers and lines by more than 15-30%, and reduce line losses by 25-50 %, achieving stable voltage, improving power quality, and reducing the cost of electricity supply and consumption.

basic skills
reactive power compensation
The sampling physical quantity is reactive power, no switching oscillation, no compensation dead zone, according to needs, use Y+△
Different combinations of different ways to compensate the reactive power of the power system, so that the power factor can be increased to above 0.9.
running protection
When the voltage of a certain phase of the power grid is overvoltage, undervoltage, or harmonic exceeds the limit, the compensation capacitor is quickly removed.
When the power grid loses phase or the voltage imbalance exceeds the limit, the compensation capacitor is quickly removed, and an alarm signal is output at the same time.
Every time the power is turned on, the measuring and controlling instrument performs self-test and resets the output circuit, so that the output circuit is in the disconnected state.
show
The power distribution comprehensive measurement and control instrument adopts a 128 x 64 backlit wide-temperature liquid crystal display, which can display relevant parameters of the power grid in real time and intuitively display preset parameters.
data collection
