Welcome to the apt Group‘s second Quarter Newsletter for 2017.
The year started strong and we have just returned from a significant product launch in Sweden. SPM Instrument is pleased to announce the introduction of the Intellinova® Parallel EN. This is a high performance 16 channel on-line monitoring system, with state-of-the-art data processing.
All-Test Pro provides an article entitled “What is 3 Minutes of Motor Testing Worth to You”. It discusses how easy a wrong diagnosis can be made if only using conventional test equipment. Whereas, the All-Test Pro 5 Motor Circuit Analyser correctly evaluates the condition of the electric motor connections, stator, and rotor in just minutes. The basis of this article is further reinforced by a local case from Boral Cement.
Lastly, we are pleased to announce dates for this year’s Motor Diagnostic Workshop. It will be run for the 12th consecutive year by Mr Bill Kruger between 28 Aug – 1 Sept in Perth; this is a must attend event for any Company wanting to improve its electrical plant reliability.
We hope you enjoy our newsletter.

Intellinova Parallel EN and Condmaster Ruby 2018!
New Products Launch
SPM Instrument, Sweden, leading worldwide provider of condition monitoring technology and products, now announces another milestone in the Intellinova® suite of systems for continuous monitoring of rotating machinery. The high-performance online system Intellinova® Parallel EN is perfectly suited for condition monitoring of industrial equipment with high availability demands.
Intellinova® Parallel EN – Reliability at work
Intellinova® Parallel EN is the most advanced system in the Intellinova® family. It is particularly well suited for applications where a critical success factor is the capacity to complete the required measurement within a very limited timeframe, e.g. due to short process cycles. With parallel and synchronous measurement capability on up to sixteen channels, Intellinova® Parallel EN is a perfect fit for applications like rolling mills, railcar dumpers, press nips or winders, as well as lifting and hoisting equipment such as cranes or drop sections. Thanks to its parallel-processing capability, relevant events are captured without delay, making the system a highly efficient solution where machine fault development times may be short.

All-Test Pro Case Study
What is 3 minutes of Motor Testing worth to you?
Author: Richard Scott, General Manager, ALL-TEST Pro,LLC.
A hospital in Netherlands rented a portable crane to install a motor of 17 Kilowatt, 400-Volt used to operate a fan that is mounted on the hospital’s roof. After one year, the motor suddenly stopped running, so the motor distributor was contacted for on-site support. The motor had been connected to a Variable Frequency Drive (VFD), and when the motor stopped running, the hospital’s maintenance technician reset the VFD. The motor did start, but the VFD shut the motor down again. The motor testing tools the technician used pointed to a “good” motor; therefore, they decided to replace the VFD. After installing the new VFD, the motor started up, but did not continue to run. Much to the technicians’ chagrin, they were experiencing the same problem and contacted the motor distributor. The service center technician used a meg-ohm meter and Digital Multimeter (DMM) to determine that the motor was not grounded and the phases were not open, since the motor still did not run, they decided to replace the motor. A crane was brought in to remove the motor from the roof of the hospital and replace with a new motor. The replacement motor started and operated normally, confirming the new VFD was working as intended.
An ALL-TEST PRO 5™ (pictured to the right) was used to perform a de-energized, non-destructive Motor Circuit Analysis (MCA) test at the service providers’ facility. Motor Circuit Analysis evaluates the condition of the electric motor connections, stator, and rotor in just minutes. Using the AT5™ connections were made to the three phases of the motor and a static test was performed. Next, the motor shaft was manually moved during the dynamic portion of the 3-phase test, and at the end of the test the instrument showed the results, where was found that the problem was between phases 2-1 (as shown on the right).
If the hospital’s maintenance team had owned and utilized a Motor Circuit Analysis instrument such as the ALL-TEST PRO 5™ or ALL-TEST PRO 33 IND™, then they would have been able to tell right away that the motor was the real problem and not the VFD. Many hours were wasted by ordering and installing a new VFD when it had not been the true cause of the problem.

Boral Cement, located in Berrima, NSW shared a similar experience where they lost 3 days of operation in their cement mill when a 315kW, 400V motor was misdiagnosed and the VSD was thought to be of blame. A new VSD was purchased in a hurry and they had the same result – the motor was still not turning. The next logical step was to replace the motor.
Since this ordeal the company has adopted the following maintenance strategies for all its LV motors.
• All maintenance electricians are trained to use the AT5.
• When a VSD trips, maintenance electricians will use the AT5 to test the motor. A 3 minute test will determine if the motor is good or not.
• Before a motor is changed, an AT5 test in the workshop is conducted to record the readings and obtain a base line for the motor.
• All 45kW and bigger motors are tested 3 time a year (when access is available) to trend results and prevent unexpected failures.
