Show formula which gives full load current 4.8 amps of a 3 HP motor and 27 amps of a 20 HP motor having 3 phase 460 volts, 0.8 Pf.
2 5211Can earth resistance be measured without connecting the earth electrode? and should earthing connections be disconnected What is the effect of connecting two cables of different sizes in parallel with supply? Thanks in Advance. I am intrested to get in touch with some tecnocrats/engineers,my mail i.d is : hiremathvijay@rediffmail.com
