Back to basics: Switchgear, transformers and UPSs· In a typical installation, LV switchgear is connected to the secondary of a power transformer — either the utility's service transformer or a facility transformer. Where service is at medium voltage, a power transformer may be close-coupled to the switchgear, with the two assemblies bolted together to form a single unit.

Gas-Insulated Switchgear Market by Voltage Rating ... gas-insulated switchgear market is projected to reach USD 26.5 billion by 2025, at a CAGR of 9.5% during the forecast period. The factors driving the growth for gas-insulated switchgear are the growing investments in renewable energy and government initiatives to reduce carbon emissions along with the expansion of electrical grids due to the growing industrialization and urbanization.
Switchgear - Environment first with SF6· The advantages of using SF6 in HV switchgear are considerable, not least because the gas is non-flammable, non-corrosive to internal switchgear components and its thermal properties make it an exceptional arc suppressant: even when SF6 is momentarily broken down during arcing, it largely re-combines back into its original state.

Gas insulated power transformers: A growing technology ... insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons.
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.
