How to Build a Static 3-Phase Converter

A static 3-phase converter is used to conserve energy. The converter breaks the electrical supply into three power phases, making it easier to regulate electricity usage, and therefore, cost. The converter charges and discharges the capacitators, creating a third phase of power. This electrical supply is used to power third phase motors, machinery, and other equipment. Before building your converter, you need to decide how it will be used because it will not work with 3-phase battery chargers, 3-phase welders, or 3-phase lasers.

Follow Safety Precautions

Before you begin, be aware of and follow the safety precautions associated with building a 3-phase converter. This reduces the risk of electric shock and could save your life. If you are unfamiliar with the necessary safety precautions, work with someone who understands what needs to occur to ensure protection during the building process.

Gather Your Materials

Gather your materials before you begin building. You will need a fuse block, a two-pole contractor amp, a one-pole contractor amp, starting capacitators, plastic tape, plugs, rubber gloves, a control power disconnect, a voltmeter, measuring tape, nails, and 9-lead motor wiring. You will want a blueprint or design to guide the building process. Coverters include three sections, the main panel, the remote control, and the auxiliary remote panel. Your blueprint should include all three components.

Begin by setting up the main panel of the 3-phase converter. Ground the frame of the converter so you can work safely. Choose your idle motor and add the run capacitors and the start capacitors. Your motor determines the type of capacitors you should use. Next, wire the run capacitors and overloads. Choose the size of the wire based on how much current you plan to use. The total drop of the voltage should not exceed three percent. Once the wires are placed, do a test run. Separate the conductors with a plug and turn on the converter.

Safety is of the utmost importance when dealing with a converter of any kind. You are working with electricity and should understand the risks involved before beginning your project. You should always wear plastic glove when working because it keeps you grounded, avoiding electrical shock. Before beginning this project, check the wiring regulations in your community. Some areas have special requirements, so you want to know in advance if it is even legal to use a 3-phase converter. Finally, make sure you have a plan in place before you begin working. Following guidelines will make building much easier and much safer.
