Choosing a three-phase electrical installation

For many businesses a single-phase power supply is sufficient. However, factories, commercial premises and specialised equipment users requiring a lot of electricity need a more stable and efficient source.

THREE-PHASE ENERGY SUPPLY FOR YOUR BUSINESS

Meeting your business’s power needs

By installing three live wires instead of one, each with offset power supplies, you can ensure continuous and balanced performance. This is ideal for high-powered equipment, but each phase is still suitable for standard installations.

One sign you need a power supply upgrade is if the lights in your premises flicker when you turn on certain equipment. Alternatively, you might find your main circuit breakers frequently trip.

Frequently asked questions

How does a three-phase power supply work?

For many properties electricity comes from one live (phase) wire, at a. voltage of 240V. This is sufficient for most needs. However, for businesses that use a lot of electricity, three live wires can supply 240V per phase. Between each phase the voltage is 400V. This provides a more reliable and larger power supply.

Will I use more electricity with a three-phase installation?

Once installed, the price per unit of electricity used in your three-phase system is the same. However, you may find that overall efficiency improves, helping reduce your operational costs.

What is phase balancing?

For best performance equal current flow across each of the three phases is important. In the design of a three-phase electrical system all electrical circuits must ensure equal distribution across all three phases. Unbalanced loads can lead to voltage drop, damage to electronic equipment and energy loss.
