It is estimated that almost half (45 percent) of global electricity is used by electric motors. Electric motors drive a considerable amount of equipment in almost all industries, from power generation to water and food supply to consumer products. The importance of electric motors in modern society cannot be understated. It is because of this vital role that it pays huge dividends to keep your electric motors running efficiently through a quality reliability program that includes energized and de-energized electric motor testing (EMT).
Until now, preventing motor failure required early retirement, as in repairing or replacing your rotating equipment on a schedule possibly years before the motor would fail. Fortunately, the declining costs of sensors and submeters, together with the growing big data industry, have made condition monitoring increasingly accurate and affordable. The net result: condition monitoring can decrease your motor operations and maintenance (O&M) expenses by up to 25 percent.1
This article describes how condition monitoring detects motor damaging situations and uses that information to maximize the life of your rotating equipment.
The Electrical Apparatus Service Association (EASA) announces its Spring 2018 educational seminar schedule. Attendance at EASA seminars is open to members and non-members.

With Simotics IQ, the new IoT concept for motors from Siemens, the new Simotics SD low-voltage motors are fitted with a compact sensor box which captures important operating and condition parameters and transmits them by WiFi to the cloud.
The Central Arizona Project (CAP) operates and maintains 109 motor/pump units in 15 pumping plants scattered across 336 miles of aqueduct. These units are indispensable to CAP’s mission of delivering Colorado River water to the people and farms of central Arizona.
Several tests can be performed on a hydraulic pump to indicate its condition. The temperature of the pump case, the flow of the case drain and the current draw of the drive motor are common checks that can be done regularly and over a period of time to track the wear of a hydraulic pump.
