Electronic Voltage Regulator Solves Voltage Regulation and Brownout Problems

Eaton's Cutler-Hammer Electronic Voltage Regulator (EVR) is the ideal solution for facilities experiencing voltage regulation and brownout problems. No one else delivers the fast response, high inrush current and operating advantages of the Cutler-Hammer EVR.

The EVR is designed to meet the needs of customers who experience voltage regulation problems due to brownout conditions on their electric utilities.

Brownouts

In the United States, most facilities have sufficient voltage regulation. However, in some US locations, and many developing countries, regulation problems occur because of over stressed utility distribution systems.

In some cases, due to the excessive demand on the utility system, voltage may be below 10% of nominal (-10%) during the day. This condition is called a voltage regulation or brownout. Customers may notice dim lights and reduced power. During the evening, voltage may rise above 10% of nominal (+10%) because large facilities and loads are shut down. This shutdown reduces the power demand on the grid and results in a voltage increase.

The Solution

Prior to installing an expensive solution, Eaton encourages customers to monitor incoming voltage to determine if voltage regulation is a problem. The local utility may also be able to provide information on voltage expected at the facility.

Using a meter, it can quickly be determined if a voltage regulation problem or brownout condition exists. The appropriate solution would be an Electronic Voltage Regulator (EVR). EVRs can be installed at the service entrance, branch panel or at critical loads.
