- Description
Minimum insulation resistance value
At a pressure of 1000 V applied between each live conductor and earth for a period of one minute the insulation resistances of HV installations shall be at least 1 Mega ohm or as specified by the Bureau of Indian Standards. Medium and Low Voltage Installations- At a pressure of 500 V applied between each live conductor and earth for a period of one minute, the insulation resistance of medium and low voltage installations shall be at least 1 Mega ohm or as specified by the Bureau of Indian Standards] from time to time. 1. IR (Min) = kV+1 For most windings made before about 1970, all field windings, and others not described below 2. IR (Min) = 100 MΩFor most dc armature and ac windings built after about 1970 (form wound coils) 3. IR (Min) = 5 MΩFor most machines with random -wound stator coils and form-wound coils rated below 1kV
Sir usefull information

Please upload the video sir for emergency
Pantrom voltage explanation bro
If 1000v means is there any different in value or same?
Different bro but concept same
