How does GIS for Water Leak Detection Work? - The Water

The problem with detection is that only bigger leaks get detected, often even they get noticed and reported after the pipe bursts. Satellites can detect leaks as small as 0.5 l/min. As well as being the most precise, they are the fastest. They do not require any manual labor nor anyone on the field.Get price

Three abnormal situations leading to an uncontrolled release

Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section “leakage from sf6 gas – filled equipment” which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the gaz sf6 in one circuit-breaker escapes suddenly and it is again assumed that the switch-room is sealed and that ventilation is inoperative. (see figure 1). In practice, attention would be drawn to an abnormal leak by underpressure detectors fitted to the CBs. These normally operate around 80% of normal filling pressure, and at this point in time, only 20% of the available sf 6 would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of gaz sf6 in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of insulating gas from one CB would reach 17,5 ppmv. The concentration of SOF2in the switchroom at 20% relative pressure loss (commonly the alarm level) w...Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in insulating gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.Get price
