MasTec Power Newsletter for Sept-Oct 2017

An impressive line up of AC Power Systems Products

During September MasTec received distribution for one of the most famous acclaimed companies in the AC and DC Power Test and Simulation Market place.

Regatron is a Swiss company and a world leader in Specialty AC and DC High Power Systems. Very few companies have these technologies.

You may have noticed also we received distribution for ITECH two months back, another manufacturer with a large range of AC and DC Low to Medium Power Instruments and Test Systems.

To show off these two new companies and several other power companies technologies that we also distribute, we are highlighting four special technology systems types for this month.

All are AC systems, however these companes also do DC systems

AC High Power Three Phase Grid Simulators
AC Low to High Power Sources for Equipment Test
AC Low to High Power Stabilisers & Optimisers
AC Low to High Power Frequency Converters

On the left and right side bars we will also add other types of technology of interest.

AC (4 Quadrant) Power Grid Simulators Hardware-Software

Regatron is the Grand Master of AC Power Systems

High wattage, highly programmable AC systems for Grid Test, simulation,

Plus DC Power Systems

Plus Battery Testing and Simulation

AC and DC Traction Systems with Regen.

Have a look at the MasTec Regatron page, you will be impressed.

If you go to the Regatron site where there is incredible detail, even more so.

Itech is a highly professional company also, making Programmable low to mid power range, AC and DC Sources, Supplies, Loads, Regen Loads, Battery Testers etc, a very large range.

plus much more

Another company that will impress.

Twintex is another professional company also making Programmable low to mid power range, AC sources.

We have many 10K + units running for compliance testing in NZ

plus much more

Belotti is an Italian company that is famous for Variacs since the 1940s.

Their Servo Variacs have been used for decades to stabilise AC power systems. We have many running in Super Yachts to stabilise Alternator Power.

Their new IGBT AC Conditioners, Stabiliser and Optimiser is a new technology step and takes them ahead of most in this industry.

Soltec has a high reputation world wide for reliable high efficiency power systems, UPSs, Conditioners.

In New Zealand they are the brand for AC Frequency Converters.

  LabVIEW Books   
Four Short PDF Books
How to program more effectively in LabVIEW

A n5th book is to be released soon, showing a full off line editor Application for Loading and Saving Cluster Constants and also a section to adjust Calibration and System Data off Line for easing commissioning.

This includes a section on setting up all Paths for an application as a large Cluster Constant, again easing commissioning, Typically a large Application will have in excess of 30 Paths to manage.

The current 4 books introduce a more thorough development of LCOP - LabVIEW Component Object Programming methods.

This method makes extensive use of Front Panel TABs, Diagram Constant Clusters as Type Defs and Enums as Type Def Verbs.

It has a built in Cluster Editor that runs either in the Program that allows remote adjustment of programs configuration files.

Using LCOP methods will simplify and establish design development plus stabilise your programs. It even make installs and maintenance easier.

Updating and expanding programs then follows a standard pattern already in the program design.

This method delineates Public and Private data clearly.

This is critical for Component Design and for low coupling and best Cohension.

Book 1 "Hidden Data", that is, cleaning up LV Program's by Removing Constants from Diagrams and putting them in Configuration Files for Loading at runtime.

This method does not use ini files but a far more robust LabVIEW centric method, not seen in other literature. It also cleans up Diagrams and Self Documents.

Book 2 "Abstraction", that is, removing complexity in the top layer of a LabVIEW diagram by building Abstracted Message Driven LV Components.

This shows how to build Message driven (Test Verbs) Abstracted named (noun) State Engine Components that are safe & robust. It also leads to better cohension of course and no/low coupling.

Book 3 "Real Time Cluster Constants Editor", that is, Removed Diagram Constants that are loaded at Run Time from a config file, can now be edited, in situ, inside the Program /or its Component while it runs, allowing tuning of programs in Real Time.

Changes made to the Constants by the editor can also be saved back into their original configuration files at run time. This addition of the Real Time Editor removes the need to exit a component or program to edit constants.

Book 4 "Low Frequency Real Time Control", is about how to use USB DAQ, DIO and DAC to control an Hydraulic RAM for Testing a UUT.

It is a close look at how to use State Engine for Control.

Simple but useful for anyone wanting to do closed loop control.
It embodies many of the LCOP methods discussed in the other three books.

MasTec Training
"LabVIEW for Everyone"

MasTec recently under took a 4 day Training course for 15 Academics, (Professors and Grad Students), at one of Oceania's largest universities.

The focus was on getting students to the point where they can undetake projects by the end of the course. A big ask. However, the focus was not on how to use all the bits inside LabVIEW to make software but the development of strategies to allow projects to be undertaken.

The MasTec Instructor has trained all over the globe and has taught over 2000 students.

He will also come to your site and do training with your LabVIEW team, using traditional or these new LabVIEW methods MasTec has developed.

MasTec Projects

Over the last year MasTec has completed 6 major projects in sites through out NZ. Several hundred hours of programming work has been completed, as well as many hundreds of hours of commissioning, site management, and installation.

All these projects involved LabVIEW at the core. However, many of these projects also include PACs, PLCs, Process Controllers, with peripherals like Servos, Actuators, VSDs, Water measurement and control, Hydraulic Control and other real world systems.

MasTec has several large projects on its books, spread out over about 3-4 years.

There are gaps in this schedule.

Many sites still run XP and Win 7 for their LABs and Production areas. MasTec is still undertaking new projects in legacy LV 6.1 /7.1/8.2 and 8.6 systems.

Major new projects are still undetaken in LabVIEW 7.1 that run in Windows 7 32 Bit OS, very successfully. LabVIEW 7.1 is still (in our opinion) the best LabVIEW ever released. Fast, efficient and stable. Win 7 32 bit OS will be available for some time. Most large corporations are still running Win 7 due to its excellent stability and IT staffs familiarity and history.

However, other projects using from LabVIEW 2010 up to the present version of 2015 SP1, which is good, but very processor hungry and much slower to develop in. We only recommend I7s CPUs with this software with SSDs for the OS and LV.

Announcement >>> Opportunity

The MD of MasTec has recently decided it is time to realign his life after 50 years of technology, to go horse riding with his wife and dogs Polly, Lilly and newly arrived Freddie.

If you have an interest in owning this important technology company, now is the time to act and start communcation.
