2006年10月18日 · 480 volts is the system voltage. 460 volts is the rated voltage of your equipment. 460 volt rated equipment is always used on a 480 volt system to account for voltage drop due to starting or line losses. In any event, you are fine. No resistors required!

2024年5月22日 · 230v 230v In a transformer with a primary connected to 480V Delta and a secondary connected in 480V Star connection, the coil voltages to the star point (ground) are 277 volts 480 / 1.73 = 277 volts.

2004年5月19日 · For instance if the applied voltage is 480 Volts, Nameplate 10 amperes at 460 V full load becomes; 10*460/480 = 9.58 amperes for the same full load. The limits per NEMA MG1 are +/- 10% of 460 V (414 min, 506 max.)

2009年6月2日 · The motor will now be wired for 460 volt operation. For either 230 volts or 460 volts the power is connected to W1, U1, and V1. Terminal layout. W5 W2 U5 U2 V5 V2 W1 V1 U1 W1=L3 V1=L2 U1=L1 Power is applied to W1, V1, and U1 for either 230 volts or 460 volts. Bill-----"Why not the best?" Jimmy Carter

2003年11月19日 · Distribution equipment, MCC's, panels, etc., are rated at 480 V. The utilization equipment rating of 460 V recognizes the obvious voltage drop that exists in distribution. System voltage, whether 600, 480, etc. are a multiple of 120 V or 120 x 1.73. Utilization voltage (575, 460, etc.), a multiple of 115 V or 115 x 1.73.

2010年9月1日 · One of our customers had a plant with a mix of 460 V motors and 575 V motors. They had a 480 V MCC and a 600 V MCC. Almost every time they re-arranged the machinery or the plant in the east sent a piece of equipment, it was the wrong voltage. We made a lot of money installing buck-boost transformers to correct the voltage.

2022年4月28日 · So, what this means is that you will see Transformers and circuit breakers with nameplates at 480 Volts (AC), and motor nameplates at 460 Volts (AC). Older 3-phase motors may actually have ...

2023年8月11日 · To convert 230 volts to 460 volts, you would need to use a step-up transformer. This transformer will increase the voltage from 230 volts to 460 volts while keeping the power constant.

2023年8月10日 · If a +/- 10% service voltage variation is allowed then the 380 volts RMS "nominal" voltage could in fact vary between 342 volts and 418 volts.Whether or not it would be safe to run a 3-phase motor ...

2022年12月15日 · The same 10 HP motor on three phase system draws the following amperage; 230 volts is a 28 amp draw, 460 volts is a 14 amp draw and 575 volts is a 11 amp draw. As you can see the higher the ...
