advantages of gis substation density sensor

The increase in demand for electricity and the growing energy density in metropolitan cities have made it necessary to extend the existing high voltage network right up to the consumer. Stepping down the voltage from transmission to the distribution level at the substations located near the actual consumers not only yields economic advantages, but also ensures reliable power supply.

  • A sensor powered by pulsed light (for gas density of GIS

    This power supply method was applied to a sensor for measuring the gas density of extrahigh-voltage substation gas-insulated switchgear (GIS) which can display the merits of an optical-transmission sensor. The sensor section of the gas density sensor, consisting of a transistor temperature sensor and a semiconductor pressure sensor, could be driven by an optical input of 2.3 mW.Cited by: 2

  • Service High Voltage Products gas monitoring systems

    Each compartment in a gas-insulated switchgear substation (GIS) typically has the same seal lengths and number of sealing surfaces and access ports regardless of its size. Therefore, each compartment is likely to leak at nearly the same SF 6 mass flow rate. Hence smaller compartments, lose pressure/density quicker in the presence of equivalent leaks.
