SF6 Zero emission
The gas sampled for testing is stored in an internal tank
The gas is compressed and returned to the original compartment
densimeter calibration
What it’s for ?
density monitor calibration
densiSCAN enables calibration of the densimeter monitors installed on the GIS and electrical equipements
it is used as transfer standard by comparison measurements of the SF6 density mesuring instruments
densimeter switches points verification
densiSCAN allows simultaneous verification of 3 relay trip points
SF6 gas refilling
densiSCAN allow filling of electrical equipment with SF6 gas directly from a cylinder by overpressure
dynamic temperature correction of pressure
Features
densiSCAN is a portable, automatic system for calibrating densistat switching thresholds. Densistats, also known as densimeters or pressure switches, are used to monitor the density of SF6 gas in high and extra-high voltage circuit breakers, as well as in metal-enclosed compartments GIS. If SF6 density falls, the efficiency of these devices can be reduced, leading to arcing and power cuts
The densiSCAN calibrator enables maintenance operators to simulate a drop in density in order to check that the thresholds – up to 3 thresholds – are correctly triggered, and that alarms are reported. At the end of the verification cycle, the densiSCAN produces a ticket a forgery-proof report including trip pressures, date, time, station name, start name, cell name and phase number of the device under test (DUT). Of course, the printed information is also stored in internal memory, even in the event of an untimely power cut
