Advantages of nh3 Network Monitor for gas-insulated switchgears

Dec 04, 2017 · Gas-insulated switchgear (GIS) is an electrical equipment that conceals traditional electrical devices in a chamber. GIS has obvious advantages over traditional air-insulated switchgear (AIS). Firstly, GIS demands less area thus reducing the cost; secondly, GIS has a longer overhaul period; and finally, GIS has higher reliability.

The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.
