Step up transformer 240 to 480
May 6, 2017 · I asked about bonding the transformer over at the Mike Holt forums, and one of the moderators (Don in Illinois) said that since it's a separately derived system it needs a grounding electrode: 24 to 48 step up transformer questions - Page 2 Don's got over 23,000 posts there, so I feel like I should seriously consider what he says.

Both have VFDs driving their spindles. The electrician is proposing reverse feeding a 480 delta x 240 delta stepdown transformer. I asked him about corner grounding and he no, so he's proposing running it as an ungrounded delta system. This sounds kind of dangerous, since in the event of a ground fault it becomes an ad-hoc corner grounded ...I have a Hardinge UM milling machine with a 480V-3PH motor. I made a dedicated phase converter for it. The converter has a step up 1PH transformer to get the 480V from the 240V. This connects to 1 1/2HP 240/480 motor. Capacitors are used for starting and balance of the third leg. It operates with an on/off switch.Jan 2, 2022 · The rating on the motor is 24.7 amp at 480v and there is a little 1hp hydraulic pump for the tracer but that is about it for load. Not a lot of electrical stuff on this machine. TLDR: Any recommendations on what transformer to get to step 3 phase 240v to 480v with a 25 amp load (20hp motor). Thanks guys. The way I'm understanding it is the transformer's job here is to step up 240 single phase to 480 single phase. *The leads on X1 and X4 are the incoming 240 volts. *X2 and X3 are jumpered together as shown on the transformer nameplate, it tells me to connect them together for the 240 volt and the 240/120 wire methods.
For example, if you have 230/240 volt A/C power available, these VFD's and digital phase converters step up the input and produce 460/480 volt A/C output without requiring an additional transformer. For an AC motor of a given horsepower, increasing the operating voltage of the motor results in a decrease in the full load amperage.The step-up transformer has 7 turns on the primary and 14 on the secondary; therefore, the turns ratio is 1 to 2, or 0.5. If one voltage and the turns ratio are known, the other volt age can be determined with Equations 14.2 or 14.3. Primary voltage Eq. 14.2 = Secondary voltage x turns ratio Step-up transformer Primary 120 v Step-down transformer to convert 3-phase 480V to 3-phase 240V. ... but inrush is greater than using a specially designed step-up transformer.

Transformer Size Calculator. When sizing a transformer, you need to know the kilovolt-amps (KVA) that your machine requires. This tool will allow you calculate the KVA that you need. This tool only evaluates common voltages for North America (ie. 24v, 120v, 208v, 240v, 480v, and 600v). If you have a Eurpoean voltage or something else that is ...Mar 28, 2013 · As such the transformer most likely is a 480v delta to 240 delta which can be easily feed in either direction. The only issue is that the taps on a common transformer built as a step down transformer will be built with the taps on the HV windings because they are on the outside with the LV winding on the inside next to the .
