"Instant linkage device for voltage over-limit warning" published in "Instrument Technology" Issue 4, 2020
In view of the lag in obtaining information from field managers in the current grid voltage monitoring, and there is no real-time adjustment mechanism for over-limit voltage, this paper establishes a set of DCBZ (voltage over-limit alarm device) and management procedures, which have the conditions to monitor voltage changes in voltage lines around the clock. Short messages are sent out through DCBZ on-site, which are identified by the data center and notified by SMS when the warning point is reached, and then the corresponding voltage adjustments are made, which provides a more convenient means for the improvement of power voltage management.

Accept the sixth review of the quality management system
2020 is the 19th anniversary of the establishment of our quality system. In late April, the company entered the sixth review of the quality management system. Because it is still in the period of strict prevention and control of the new crown pneumonia epidemic, our company has not accepted ordinary challenges.
