Multi-channel dc watt-hour meter and risk detection method thereof

摘要

Disclosed are a multi-channel DC watt-hour meter and a risk detection method therefor. The multi-channel DC watt-hour meter includes: a conversion unit that receives a raw measurement signal from a measurement unit installed in a power line that is a main line or a branch line for supplying DC power and converts it into a converted measurement signal; an AD converter that converts the converted measurement signal into measurement information in the form of a digital signal; and an analysis unit that applies a predetermined analysis technique to the measurement information to analyze whether there is an overcurrent and a DC arc current in the power line, and transmits the risk information to a predetermined receiving device when a predetermined condition is satisfied do.
