SPD for Power Supply System Series Selection Guide The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity. The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.

Djx supplies graphite plate for spd surge protection device with various sizes, customerized products are available depending on your pictures and drawings, we will recommend the most suitable graphite material for you, please contact us for more details. Based on the disadvantage of traditional gap surge protector (spd), and combined with the material characteristics of graphite and thompson gas discharge theory, a large scale of experiments on the new type of graphite gap spd were completed by open circuit voltage wave generator and icgs impact system. The results show that, after the high voltage trigger capacitance device was added to the new type of graphite gap spd, every gap was triggered step by step so that the voltage protection level was reduced. At the same time, the graphite gap spd is better than traditional gap spd on time delay characteristics, and is able to achieve the arc extinction requirements before the power frequency voltage dropped to zero. In addition, graphite belongs to non-metal materials; it won't produce plasma under high temperature, which can improve the stability of device and delay aging.
