摘要： The present disclosure provides a direct current (DC) transformer error detection apparatus for a pulsating harmonic signal, including a DC and pulsating harmonic current output module and an external detected input module, where the DC and pulsating harmonic current output module outputs a DC and a DC superimposed pulsating harmonic current to an internal sampling circuit and a self-calibrated standard resistor array; and the internal sampling circuit converts the input DC and the input DC superimposed pulsating harmonic current into a voltage signal, and sends the voltage signal to an analog-to-digital (AD) sampling and measurement component through a front-end conditioning circuit and a detected input channel. The DC transformer error detection apparatus can complete self-calibration for measurement of the DC and the pulsating harmonic signal on a test site.

摘要： Disclosed are an online analysis system and method for a line loss of a transmission line. The system includes: a terminal extension and a terminal host, where time information synchronization between the terminal extension and the terminal host and between terminal extensions is performed by a clock synchronization module, and communication between the terminal extension and the terminal host and between the terminal extensions is performed by a communications module; and a line loss management platform, configured to receive measurement data of the terminal extension and the terminal host, match time information in the measurement data, and if time information in the measurement data of the terminal extension and the terminal host is matched, and time information in measurement data of the terminal extensions is matched, determine corresponding line loss information based on corresponding measurement information.
