Technical Article: Voltage Drop In a Facility
|
From Utility Systems Technologies, Inc.
It is expected and accepted (in the U.S.) that there will be a voltage drop of 3 to 5% from the point where the electric utility delivers power to the end user (usually at the meter) to the point within a facility where the electricity is finally consumed in an electrical device (the load). Unlike utility voltage levels which may be high or low, the voltage drop due to wiring impedance within a building will always drive voltage levels lower. For example, if the incoming utility voltage is 5% low, the voltage at the point of usage might be 8 to 10% (5%+3% to 5%+5%) below nominal due to the voltage drop within a building. AC motors are commonly rated at 460V (480V-4%) rather than 480V to address the voltage drop in a facility - and to optimize motor performance. Products & Services
Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.

Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).

Line conditioners, also known as power conditioners or power line conditioners, are regulators that protect equipment from excessive fluctuations in the utility line, or power system voltage.
Learn more about Line Conditioners
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.
