Where Does Twice-Line-Frequency Vibration Come From?

Where Does Twice-Line-Frequency Vibration Come From?

An hour long presentation by Jason Tranter, Managing Director, Mobius Institute

Have you ever wondered where the twice-line-frequency peak (typically 120 Hz or 100 Hz) comes from in the spectrum? It can indicate a fault condition, and it can be confused with other fault conditions - and it can mean absolutely nothing! In this presentation we hope to clarify two issues; why does the peak appear at twice the line frequency, and which faults are indicated by the appearance (or growth) in the peak at that frequency. In addition to understanding the origin of the twice-line-frequency peak, you will learn a little about magnetic fields and how three-phase induction motors work. As always we will use 3D animations and simulations to make the topic easy to understand (and interesting to view).

Online Condition Monitoring

Online Condition Monitoring

A forty minute long presentation by Robert Dent, CMRP, Commtest

Online Condition Monitoring can provide reliable and repeatable information on assets where an increased frequency of data collection is required due to its criticality or its potential failure rate. Online Condition Monitoring can also provide access to data from areas that are deemed unsafe or hazardous to collect information by portable methods.

PowerHawke, Inc. Broadens Arc Flash Product and Service Offering

FARMINGTON, CT, September 7, 2012 - PowerHawke, Inc. announced today that it had entered into an agreement with IRISS, Inc., a leading manufacturer of infrared (IR) inspection window technology, to become a New England, Level I Partner for their product line. The line is comprised of numerous sizes, shapes and configurations applicable to a wide-range of equipment in most critical power systems. PowerHawke will be focusing the majority of its efforts in the electrical space although the IRISS product line cuts across many types of applications.

Vibration Monitoring of Wind Turbines

Vibration Monitoring of Wind Turbines

An hour long presentation by Jason Tranter, Managing Director, Mobius Institute

Given their remote location and the extreme operating conditions, the successful monitoring of wind turbines is a critical pursuit. However, they do present a number of challenges, including: they vary in speed and load, they have high speed and low speed components, they include a complicated planetary gearbox, they resonate, an on-line monitoring system is required, and costs must be minimized due to the number of turbines being operated.

Optimizing Bearing Life with Precision Lubrication

Optimizing Bearing Life with Precision Lubrication

A forty-five minute long presentation by Jarrod Potteiger, Educational Services Manager, Des-Case Corporation

Getting the optimum life from bearings is somewhat uncommon. Many maintenance professionals don't even realize how long bearings should last in a given application. Unfortunately, many focus on failure prediction and repair efficiency when they could be preventing failures in the first place. In order to achieve longer bearing life, one must understand the common root causes of bearing wear and learn how to eliminate them.

Trend and Monitor Rotating Equipment with Ultrasound

Trend and Monitor Rotating Equipment with Ultrasound

A forty-five minute long presentation by Paul Klimuc, SDT

In this webinar you will learn the basics used to trend and monitor rotating equipment for predictive maintenance using ultrasound equipment. We will cover how to setup a database for trending data, where to set alarm levels and how to monitor lubrication in conjunction with incipient bearing failure.

This article is written as a follow-up to the April/ May 2012 Uptime magazine article titled, "When Decibel's Aren't Enough." In the previous issue of Uptime, we told the story of testing eight, 50 hp filtration pump and motors at a local waterpark.

Using Acoustic Emission Enveloping to Detect Lubrication Defects

Using Acoustic Emission Enveloping to Detect Lubrication Defects

An hour long presentation by Robert Collyer, Principal Engineer, SKF

SKF Acoustic Emission Enveloping should be used along with the measurement of other data as part of a multi parameter approach to provide a holistic assessment of a bearing or a machine's health. Acoustic emission enveloping technology can detect lubrication defects and improve machinery monitoring, providing a valuable indication of unhealthy or damaging running conditions that can be corrected or improved. Traditional vibration in most cases indicates that damage has already occurred.
