The equipment is wired for 250 amp 400 volt service. I need to know how many amps it would pull after using a transformer to step it down to 220v 3 Phase. If I use the general equation Watts = Volts X Amps I get 100,000 watts. If I plug that number into the equation using 220v I get 454.5 amps (100,000/220 = amps), which seems like far too much.
400V Delta primary (input) x 120/240 secondary (output). 3 phase, 50hz and 60hz available, dry type open and enclosed (Nema 1 - Rated for indoor use) available. Dry type distribution transformer. 400V Primary - 120/240 Delta Secondary (with center tap) kVA. Output Voltages.
#1 Hi everyone, I want to install 400V HPS light (600W) on site without three phase supply. I looked at step-up transformers and various inverters but I couldn't find one which takes 230V a.c. and gives 400V a.c. and is rated at minimum 0.6kW.
Devices charging slowly. Electrical outlets not working. Flickering lights. Scorch marks on outlets and light switches. If a circuit breaker keeps tripping in one room, homeowners can test for
As I remember, the calculation of the "Phase to Phase" Voltage is (if the "hard drive" is still working properly ) Square root of 3 multiplied by the "Phase to neutral" Voltage or. sin 120° x 230V (Phase to Phase Voltage); 1.732 x 115 = 199.186 V or. 0.866 x 230 = 199.186 V. So the "Phase to Phase" voltage of 120V should be;
Three Phase AC (Isolated) These colors are used for multi-phase 277 & 480V in Canada. ORANGE = Phase 1 or Line 1 âL1â. BROWN = Phase 2 or Line 2 âL2â. YELLOW = Phase 3 or Line 3 âL3â. WHITE or GRAY = Neutral âNâ. GREEN, BARE or GREEN / YELLOW = Ground âPGâ. cSfRh. 27398318444495367370297377
