ENSPC Three phase unbalance automatic adjusting device Model description EN SPC 75 / 400 - 3 ¨C W EN: Company code SPC: Three phase unbalance adjustment 75: Capacity: 35kvar,50kvar,75kvar,100kvar 400: Voltage grade: 400V 3: 4:Three phase four wire 3:Three phase three wire W: Outdoors

It is very common for three phase unbalance in the low voltage distribution. In the urban network and agricultural network, due to a large number of single-phase load, and it is extremely serious for three phase current unbalance phenomenon. The current unbalance in the power grid will increase the consumption of lines and transformer, lowering the function of transformer, affecting the safe operation of transformer, as well as zero drift, which may lead to three phase voltage unbalance, thus to lower the power supply quality. For the above mentioned condition, in order to optimize the power quality, saving energy and reducing emission, we has specially designed three phase unbalance automatic adjusting device. This device can filter more than 90% of the zero sequence in the rated capacity, and control the three phase unbalance degree within 10%.
