At present 10kV high voltage (HV) energy meters apply optical fiber communication or wireless communication technology to transmit data on distribution line. However optical fiber cable with high cost is damaged easily, Wireless communication which includes micro-power RF and GPRS is utilized for 35kV HV energy measuring device to transfer local and remote electricity information, and is analyzed of its key design points and main functions. Wireless calibration is put forward to increase its safety and reliability and decrease hardware cost.
