Gas insulated substation (GIS) versus Air insulated ...· 2. Maintenance. The failure rate of circuit breaker and disconnecting switch in GIS is one-fourth of that of AIS and one tenth in case of busbar, thus the maintenance cost of GIS is less than that of AIS over the lifetime. 3. Operation cost. The maintenance cost of GIS and AIS shall be equivalent.The cost for training in GIS is higher than in AIS.

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.
