Great Expectations!
(Or, how commissioning can go wrong)

We deal with a wide range of projects in NZ, and often get to see how reality doesn’t necessarily line up with project expectations of commissioning sites on time, and within budget. Some of these we call “great expectations” when considering the highly technical and tightly integrated equipment that is being applied, the lack of adequate test plans, and often a total lack of familiarity with the equipment.

We do not believe on-site commissioning is the time, nor the place, to do the learning, nor is it adequate to have the equipment turn up a few days prior for a small bench test session. Last month we advised that our new REG-D/DA Testing and Commissioning Courses will be based on customer specific test plans to ensure, firstly that staff involved actually have a thought-out test plan, and secondly, the technicians / contractors are familiar with the specifics of the project (or preferably the specifics of the Utility’s standard design that applies to all future projects).

We are interested in feedback on this approach, especially if you have ideas of how to leverage better on-site efficiency; perhaps there are training or practical schemes that can accelerate the learning process?

Some industries have schemes involving skill certification, where the equipment supplier can audit and certify staff to a certain level of proficiency with software or hardware. Perhaps, in the future, a utility’s project engineer could ask the question “are those techs ‘black’ or ‘brown belts’ in Voltage Regulation?” We suggest there would be real merit in knowing a black belt is assigned to a specific project task.

It makes no sense to pay the added cost of project delays while staff get up to speed – on the job!

Next month, we will talk about “TeamViewer” software. We’ve found this highly productive when field engineers and technical staff have wireless modems and laptops which allow sharing of desktop views. The ability for us to remotely “look” at your laptop to see what’s going on, and for you to see our desktops to give you a view of how to perform a particular software process, has proven to be a very, very effective method of technical support.

      Prepare for the CMIC RTU!    
     
Siemens CMIC mini RTU

We are highly confident that the SICAM CMIC is going to become a useful building block for many of our customers. Designed to fit in the Siemens 8DJH Ring Main unit to provide advanced automation and RTU capability, its many features will also make this product incredibly useful for other applications within the Power industry.

Key Features:

  • 12 Digital inputs (24-60 V)
  • 8 Digital Outputs
  • Power Supply 24-60 Vdc
  • RS-232, RS-485 & 2 x Ethernet Ports (copper)
  • Supports DNP Serial and DNP-iP protocols (IEC 101, 103, 104 & MODBUS also supported).

The CMIC uses the SICAM Toolbox for the programming of the SD card (offline parameterisation), or via Ethernet or remote serial engineering access for direct access. The CMIC also features a built-in web browser to allow local review/setup – simplifying and lowering the cost of maintenance!

The SICAM CMIC is not just an RTU I/O unit, but supports local automation via PLC functionality. Using a standardised IEC 61131-3 graphical editor, a comprehensive library of functions is available, allowing you to develop logic for switching/automation and control.

The future for SICAM CMIC looks very bright, especially as we expect to see analogue mA input options and IEC 61850 protocol incorporated in the coming months. The CMIC will also function as a DNP/IEC 61850/MODBUS protocol converter. Contact us if you can't wait!

 

   
      Tekron International - Isolated Time Repeater    
     
Tekron ITR Isolated Timing Repeater

Tekron are releasing their Isolated Time Repeater (ITR) to replace the MOFR series. The ITR Series are designed to provide a higher power output drive and lower input burden. These changes have been identified as beneficial when routing very precise time bus signals, for applications such as synchrophasor measurements.
Key improvements:

  • Input burden reduced from typically 7 mA to 2 mA
  • TTL output drive increased from 75 mA to 150 mA

Roughly - where one MOFR could drive a daisy chain of 10 MOFRs, the new ITR can drive over 7 times this number of ITR’s! You can safely use a mix of MOFR & ITR’s in your time bus applications. The ITR series are constructed using the same enclosure as the MOFR, and for most applications there is a 1-to-1 equivalent. However there are some differences:

  • The output terminals are arranged in a different order
  • The AM IRIG-B isolation transformer is no longer provided
  • HV MOSFET output is only available with a Copper+Fiber Input – there is no ITR with Copper-only input and HV MOSFET output
  • Internal resistor for input termination (using TERM connections) is now 120 ohm (was 150 ohm)
  • The ITR has a ground terminal to provide improved surge protection to the power supply input. This ground terminal is also the common signal terminal for RS-232 & TTL outputs

      REG-D/DA Design Workshop 29th November 2013    
     
REG-D and REG-DA Training for 2014

This Design Workshop is aimed at the design engineer who seeks to gain an understanding of how to integrate the voltage regulator into their project, what design considerations should be taken on-board to develop a “standard” design, and how to calculate the settings required. 

The Design Workshop covers the performance and physical connection requirements for voltage regulators. Different topologies will be discussed, allowing designers to understand the appropriate design for different applications. The Design Workshop will cover the basics of transformer paralleling and temperature monitoring/control. This Workshop is critical for those wanting the practical knowledge on effective and efficient transformer control designs. The course is suited to designers, graduates and engineers.

This Auckland course will be limited to 6 participants. Register your interest by Friday 15th November to vladimirb@hvpower.co.nz , or phone 09 304 1685 (mobile 021 277 1035).

Services Section 2 REG-D/DA Design & Commissioning Tools

Our website Technical Library has a new tool to help your REG-D/DA Voltage Regulator Commissioning:

TMM temperature/time response:
This spreadsheet produces a time curve of REG-D/DA voltage regulator TMM time response. Enter the appropriate transformer data, regulator and test settings, and test points will be provided. Training on this tool, TMM functions, and how the different cooling levels operate are covered within our REG-D/DA Advanced Training, REG-D/DA Design Workshop (see above for details on our November Design Workshop). However, for simple single cooling level applications, the spreadsheet alone without any training will be sufficient for many.

Click here for HV Power Technical Library website for spreadsheet download (look in the software section).

Services Section 3 The simple guide to Termination Resistance with MOFR & ITR's

For all but high accuracy synchrophasor applications, the following guide to termination of IRIG-B Time Sync Bus’s should be sufficent:

DCLS IRIG-B (B0xx): DC Level Shifted;

  • Use shielded twisted pair cables, such as Belden 9841. The key specifications are 120 ohm impedance and low capacitance
  • At the end of the Time Sync Bus, terminate with 120 ohm resistance
  • For higher accuracy, use an oscilloscope and looking at ringing or undershoot, adjust termination resistance accordingly
  • Ensure the total loading on the time bus does not exceed the drive capability of the source (150 mA for Tekron Clock and ITR, 75 mA for MOFR)

For DCLS systems, the main goal of the termination is to match the impedance of the cabling. Shielded twisted pair, or twisted pair wiring, is more convenient and preferable to coax.

AM-IRIG-B (B1xx)

  • Use shielded twisted pair cable. If you must use coaxial cable, then use 75 ohm coax due to its lower capacitance
  • Use the Tekron spreadsheet to determine the termination resistance (based on drive voltage, the number of IED’s and their input resistance)
  • In the absence of any information, a termination resistance of 100-180 ohm can be used for time sync buses connecting to 20-30 IEDs

For AM-IRIG-B systems, the main goal of termination is to ensure the correct voltage levels are being provided to the connected devices. The termination resistor is used to load the source so the AM IRIG-B signal level is in the “sweet spot” for the IED’s.
