Company:

Descon Engineering Limited, Pakistan

Segment:

Power generation

Task:

Position sensors for detecting the gate inclination at the dam flaps of the Khanki Dam in Punjab, Pakistan. It is extremely important for the application to use resistant materials as well as to obtain stable position signals. The application is a hydraulic structure with strong vibrations, a temperature range of +10°C to +45°C and a humidity of 70% to 90%. It is also important to the engineers during commissioning that the sensors can be integrated into the control room in a very simple and straightforward manner. Long-term stability as well as a long service life of the sensors is a prerequisite.

Solution:

KINAX®-N702-INOX inclination transducer with oil-damped pendulum system. This type of inclination transducer is extremely robust and very well suited for such type of environmental conditions as well as application.

Benefit:

Due to the high-end engineering on the part of Descon, technical parameters lead to the advantages. These are, among others, the range measurement in an angle 0….359°, the stable output signal 4 to 20 mA, the high accuracy of 0.2°, the material composition of the housing, the withstanding of vibrations due to the oil damping (vibration resistance: <40m/s2 / 10. …500 Hz according to IEC 60068-2-6), a shock resistance <300 m/s2 / 18 ms according to IEC 60068-2-27, a temperature range -30…+70°C, humidity <100% and a temperature drift 0.1°/10K.

Company:

Bejing Capital Airport (PEK), PR China

Segment:

Airport

Task:

In the People’s Republic of China, the state awards the so-called Green Label to demand efficient energy consumption. With a view to saving energy on a massive scale and thus conserving valuable resources, Beijing Airport has converted its lighting from energy-guzzling lighting systems (e.g. gas pressure lamps) to LED technology. Since the changeover, however, the technical management has noticed that the service calls of the technicians have increased many times over. And what’s more, the service calls have changed in that more malfunctions have occurred in the context of electronic controls and IT systems. Often, malfunctions could be resolved by a simple reset. However, it was not possible to determine what had caused the malfunctions. And the frustration of all involved was great.

Solution:

After several discussions with the technical airport management and the incidents, it was clear that the LED systems had changed something fundamental. However, where, when and why disturbances were occurring could not be determined until now. For this reason, it was decided to carry out continuous voltage quality measurements with the LINAX^® PQ5000 at many critical distribution points within the airport grid. The basic prerequisite for the pilot and subsequent roll-out was compliance with all technical specifications as well as simple system integration.

Benefit:

Thanks to the continuous measurement and the integrated time synchronization, it was possible to determine where possible causes came from in the event of a malfunction. In fact, the new and modern LED lighting was mainly responsible. Quick intervention at the cause, e.g. by using filters, higher quality systems, etc., reduced the number of faults many times over. However, the measurement did not only help reactively, but was also used as a preventive measure to avoid disturbances before they occur. In addition, due to the accuracy of the measurement, the load flows could be controlled and optimized. This is also part of the Green Label. For the roll-out and ongoing implementation, the user-friendly HMI was very beneficial for the customer. Last but not least, Beijing Airport relied on Swiss precision certified by METAS as well as the comprehensive cyber security at the device level – a true brand label.

Segment:

Holders of an electrical installation permit (electricians, inspectors, etc.)

Task:

Since 01.01.2018, the partial revision of the NIV (Low Voltage Installation Ordinance) adopted by the Swiss Federal Council has been in force for holders of the general installation permit. This also prescribes regular further training for holders of a restricted license. The obligation to undergo further training is one day per year.

Solution:

In order to give the holders of an installation permit the opportunity to continue their education on a smaller scale, the Academy was founded in 2019. The Academy offers seminar participants state-of-the-art ambience and seminar technologies to enable effective as well as efficient learning. The individual lessons are held by professional speakers with proven expertise to offer real, relevant as well as interesting topics. Up to 50 participants can join the table on site. The seminars are also held in hybrid form. This means that participants can also take part via a webinar. In addition, participants can have their measuring instruments calibrated on site and take them home again on the same day. Participation is confirmed with a certificate.

Benefit:

The Academy with its location in Wohlen in Aargau offers good transport connections from all directions. In addition, the train station is only a few minutes’ walk from the venue. Those who want to avoid the journey to and from the event can also participate in the seminar online at any time. External advisers provide thereby for an interesting and instructive program. The hospitality of the participants starts in the well-equipped cafeteria with a welcome coffee and a traditional croissant. During the seminar there is plenty of water available for everyone. For the lunch break we currently offer a Swiss bratwurst from the outdoor grill and a salad buffet. Throughout the day, we are also concerned that the participants as well as the speakers can exchange ideas and network. Last but not least, the on-site calibration service is also a benefit. The instruments will be calibrated on the day of delivery and therefore there will be no additional freight costs or even a breakdown over several days or weeks.

Company:

Sharjah Municipality, United Arab Emirates

Segment:

Wastewater treatment (sewage plant)

Task:

Wastewater treatment and the removal of pollutants is a special task for authorities, regions, cities and their operators. Especially in desert states, such as Sharjah, where the high outside temperatures and sun exposure are added as a special challenge to the actual cleaning and disposal issue. Wastewater treatment also requires a lot of energy and, due to the many technological electronic components, is increasingly vulnerable to poor or irregular voltage quality. For this reason, Sharjah Municipality has decided to demand transparency on the topic of power quality as well as load flow optimization.

Solution:

In the first step, a LINAX^® PQ3000 was installed in each of the low-voltage (LV) switchgears on the secondary side of the 2,500kV transformers. The Power Quality Instrument (PQI) complies with IEC61000.4.30 Ed. 3 to Class A and is also metrologically certified. This means that the class A devices can withstand any technical as well as legal evaluation. The load curves are monitored via the web browser as well as via Modbus TCP/IP. The conformity of the voltage quality according to EN50160 is evaluated cyclically via a scheduler without additional software and stored in a PDF report. In addition, the voltage events are logged sustainably and can be analyzed directly via the devices.

Benefit:

The self-sufficient system of the power quality instruments with all the functionalities fully convinced the customer in terms of price and technology. Furthermore, the designated functionalities of a cyber security in the measuring device itself were very welcome. Not least because wastewater treatment is part of the critical infrastructure and must be protected against unauthorized access to a particular extent. In a further step, the measuring points are connected to a visualization and data management software, which fully covers the energy management as well as the secure data communication to the higher-level control system.
