SF6 gas in medium-voltage switchgear | T&D ... - Siemens USA is also used in gas-insulated substations (GIS) and gas-insulated lines (GIL), highly suited to urban power transmission applications. In the medium-voltage realm (up to 38kV), SF6 has been used outside the United States for circuit breakers having relatively low interrupting ratings.
What is HIPOT Testing (Dielectric Strength Test)?· Other examples include identifying a pinhole defect in insulation or finding an enlarged solder footprint. As per IEC 60950, The Basic test Voltage for Hipot test is the 2X (Operating Voltage) + 1000 V The reason for using 1000 V as part of the basic formula is that the insulation in any product can be subjected to normal day-to-day transient over voltages.
