Abstract

Adopting the sensor technology and digital circuits

a digital SF6 gas density on-line monitoring device is developed and connected into the integrated automation system of substation to realize remote and on-line monitoring. The new device may efficiently solve the problem that mechanical density relay fails to adapt real-time monitoring of equipment’s operation state in a unattended substation. It is beneficial to state-reconditioning of circuit breaker and safe operation of electric networks.
