SKF Online Motor Analysis System - NetEP Continuously monitor critical motor systems 24 hours a day, 365 days a year, from a central office – or from anywhere in the world Introduction The SKF Online Motor Analysis System NetEP is a permanently-installed machine system monitoring solution. It continuously acquires health and performance data on electric motors and the rotating machine systems they operate. With the NetEP, maintenance professionals can safely gather performance data on critical motors around the clock, 365 days a year. They can monitor the condition of motors and the rotating equipment they drive from the convenience and safety of a central office. The system helps reduce costly unplanned downtime by providing information that improves maintenance decision making and planning. The NetEP system represents a new paradigm in predictive maintenance for rotating equipment. It enables an organization’s critical motor assets to communicate if and when they are malfunctioning or experiencing a problem that could lead to failures or downtime. Motor maintenance programs are too often characterized by reactive approaches to motor failures, and rely upon periodic tests to troubleshoot a given motor’s condition. These snapshots often help to determine if a motor requires replacement or repair, but the data acquired often doesn’t reveal certain motor system issues that impact motor performance or and lead to failure. The NetEP goes beyond what portable testing does to provide a timeline of trend information that maximizes visibility into motor system health and performance. Maintenance professionals can use NetEP to monitor motor system performance from virtually anywhere The NetEP helps avert unplanned downtime and reduce motor maintenance costs with continuous monitoring of motor performance and health in the world with a PC using the system’s Web-accessible interface. Because the NetEP is a stationary system with permanent connections to motors, it makes it safer and faster for PdM personnel to monitor motor conditions. Maintenance route testing can be reduced or eliminated, allowing personnel to focus on motors the NetEP identifies as having potential problems. The system can also be used to continuously supply motor system data to an OPC standard server for use with an organization’s unique maintenance management and asset analysis

from a single desktop or laptop screen. How NetEP works Motor systems include three fundamental elements: the power source, the motor, and the mechanism that places a load on the motor (e.g., a pump, or fan). The NetEP monitors motor systems for any degradation of performance, poor power quality and adverse load conditions. It generates alerts for environmental factors such as excessive heat on a given motor’s operation. The NetEP tracks motor on/off cycles, determines load mismatches and identifies any adverse load oscillations or overloads. Performance data and problem notifications are promptly...

Data acquisition, management and trend analysis Surveyor NetEP software delivers data at regular intervals on more than 100 motor condition parameters, and can be set with alarms on up to 38 of them. Some parameters can be set to acquire trend data every ten seconds, while others can be set to gather data once per hour. The software displays the time and date of all collected data as well as start-stop times of every machine monitored. The system gathers parameter data from each motor connected to the NetEP in serial, and automatically starts over again for a new round of data collection. When...
