With the construction of ultra-high-voltage direct current (UHVDC) transmission lines, the complex electromagnetic environment around the lines has been a widespread concern. The ZigBee-based field measurement system is widely used in ground space charge density measurements of HVDC transmission projects. In actual use, the power consumption of the space charge density measurement system is a key limitation of the device performance.Research on low-power and energy-management strategies of this measurement system can improve the device lifetimes. This capability is very important for improving monitoring efficiency of the surrounding electromagnetic environment of HVDC transmission projects.
