High Voltage, Low Power Consumption: Advantages of Higher Voltage in Electrical Equipment


The regular consumption of voltage for power outlets varies throughout the world. In large commercial and industrial buildings, electrical installations use higher voltages such as 277/480V and 347/600V. The usage, utilization, and consumption of power outlets regularly make us wonder, “How long can we rely on our resources?” Isn’t it the right time to start conserving energy before it gets too late?

As they say, when there’s a will, there’s a way! Now you can achieve higher performance and a maximum voltage supply with the right equipment.

Meeting today’s need and looking forward to future requirements: Various factors determine power transmission in the market arena, including saving renewable energy, the expansion and interconnection of grid infrastructures, and the need to replace and upgrade aging grid infrastructures.

Discover how high voltage supplies can help give you efficient, reliable, and flexible power transmission:

Benefits of Lowering Current in Electrical Circuits: Office equipment, industrial machinery, and heavy electronic equipment consume more power compared to home appliances. If a low voltage- 120V is used in this case, a very high current is required to deliver enough power.

For instance, a 900-watt home appliance requires 7.5 amperes of current at 120V, but a 150-kW industrial machine would draw 1,250A at 120V.

Such a high current requires very large conductors, wasting copper and making the installation much more expensive.

On the other hand, a 600V power supply cuts down the current to a much more manageable value of 250A. If the 150-kW equipment uses a three-phase voltage, the rated current is reduced even further to 144A, while requiring an extra conductor.

Also, keep in mind that circuit breakers are sized based on current. For example, a 1250A breaker is considerably more expensive than a 250A breaker. Larger protection devices are also bulkier and more substantial, which makes their installation more daunting. Current reductions help save on wiring and electrical components.

Handling High Voltage Cautiously: To ensure continuous safety of high voltage installation, test the insulation at regular intervals. Damaged insulation increases the risk of an arc fault, creating havoc among personnel and equipment safety. 

Energy Efficiency: Can you live in darkness, or in a place where there’s no light? Can you imagine a day working at the office without internet connectivity? If no, then take measures to conserve energy. Remember, high electricity consumption is dangerous and can wreak havoc on the environment and cause an inability to meet day to day needs.  When designing electrical installations, remember that high voltage power supply reduces current, which offers protection to devices.
