Pay attention to the following points when measuring the ground resistance: The distance between the current probe and edge of the ground grid is d1, which is 4 to 5 times the maximum diagonal length (D) of the ground grid. The distance between the voltage probe and edge of the ground ...
A USG12000 chassis receives power from the AC power distribution frame through the power distribution unit (PDU) installed in the cabinet. High-voltage DC (240 V DC/380 V DC) power supply mode: Generally, a rectifier system obtains three-phase 380 V AC power input from a mains power ...
A compensated current comparator system to establish the United States legal unit of electrical energy at the National Bureau of Standards at energy levels of approximately 30 and 60 kJ is described. Analysis of the system uncertainties and experimental data indicates that the registrations of three ...
