Answer / Ajay Singh Chauhan

"Insulation levels in electrical systems refer to the voltage class of the insulation materials used. The most common insulation levels include Class 1 (up to 600V), Class 2 (up to 1000V), and Class 3 (above 1000V). These classes are typically measured in volts (V) for AC systems, and peak voltage (pk-V) or working voltage (WV) for DC systems."}
