The Basics of Switchgear : East Coast Power Services Basics of Switchgear. For those who don't know, electrical switchgear (sometimes just called 'switchgear') is a fairly broad, generic term that includes a variety of switching devices used to protect your power system from overloads. By extension then, the definition could also include devices used to regulate, meter, and control your power system.

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.
Concept of Power Electronics | Electrical4U· Apart from this ON state and OFF state losses, there are switching losses also in power electronic devices. This is mainly while the switch toggles from one mode to another and V and I across the device changes. In power electronics both the losses are important parameters of any device and essential in determining its voltage and current ratings.
