Monitor and trend the most common cause of motor failure with MSIM
For motors above 4 kV output, the most common cause of failure is stator failure, which was previously impossible to monitor while the motor was running.
The Motor Stator Insulation Monitoring (MSIM) system that slots into your existing Bently Nevada 3500 rack provides continuous monitoring of motors up to 7.5 kV and 1000 Amps.
Stator winding health is the key to reliability in motors and 66 percent of all failures in motors above 4kV were found to be caused by stator failures, according to a 2001 Allianz survey. In smaller motors they made up 25 percent, behind rolling element bearings.
By measuring the current leakage across all three phases of an AC motor, an accurate picture of the health of the asset can be determined, allowing planners to make arrangements in advance to repair or replace the unit.
The MSIM card monitors and trends stator health, which is brought into System 1 along side other condition monitoring data.
To find out how your 3500 rack capabilities could be expanded to include motor stator monitoring, contact Michael Casserly.
3300 rack monitoring system retirement
GE Bently Nevada's 3300 rack monitoring system has now been moved to 'Phase 5' of its product life cycle and is no longer supported for repairs or spare parts.
The system, which was released in 1988 has been succeeded by the 3500 monitoring system. For plants with embedded systems, a hybrid approach of 3300 and 3500 technologies is possible through the 3500 ENCORE.
To find out more about the retirement of the 3300 range and upgrade options, contact Michael Casserly.

VANZ Conference 2015
The 2015 Vibrations Association of New Zealand (VANZ) was held last week in beautiful Taupo. NVMS were proud major Sponsors again this year and were able to showcase our GE Commtest, GE Bently Nevada and GE NDT product portfolios.
Barry Shaw & John Lawrence conducted a number of practical, hands on vibration analysis sessions during the awareness day. These were well received by everyone who attended.
The conference was well attended with over 125 delegates who enjoyed the various condition monitoring presentations. NVMS would like to thank everyone who participated in making the conference a huge success and look forward to supporting this event next year.

Noise Sentinel Info Night
On May 28, NVMS ran a Noise Sentinel information evening to show how the product could help simplify environmental noise monitoring.
Silver Kenny from South 32 Worsley Alumina delivered a case study that demonstrated how community noise complaints decreased by 74% after installing the systems and community relations websites at their mine. The case study was followed by a live demonstration of the system's capabilities.
To find out more about the Noise Sentinel and Noise Sentinel on Demand ranges, or to get an in-office demonstration, contact Nick Trappitt.

 USM Go, Go+, 36 firmware update
A firmware update that corrects an incorrect amplitude readings while pressing the "freeze" button is now available for GE's ultrasonic units, USM Go, USM Go+ and USM 36.
USM Go, USM Go+, and USM 36 portable ultrasonic flaw detectors will display an erroneous digital echo amplitude % value, when used at a steel L-wave velocity at greater than 1500 mm sound path upon pressing the freeze key.
The A-scan is unaffected and correct; however the digital echo amplitude will be shown and reported erroneously. The error does not occur if the freeze key is not utilized.
More information and a link to the firmware update can be found on our website.
Retirement notice
USM23/25 and USD 15 UT flaw detectors are to be retired from service.

Safely transporting your sound level meter
Whether you’re sending your sound level meter up to site or to a calibration laboratory, shipping an instrument worth thousands of dollars can be nerve-wracking. Freight companies never guarantee safety and freight insurance covers up to only a few hundred dollars at most, so it’s important to pack instruments carefully.
If in doubt, over-pack: it’s better for your instrument to arrive in safely in five layers of packing than damaged in two.
