| Abstract: | Over-voltage online monitoring system applies real-time voltage signal of which the voltage transducer extracted from the capacitor screen tap of HV bushing of the running equipment. Through sampling under frequency conversion acquisition card,the data of transient voltage is recorded onto the tidy-capacity register. The monitoring system is compact in size,accurate in measurement,with good transient characteristics and reliable. Running practice has proven it can fulfill the long term continuously monitori... |
