- THE SMARTSENTRY® SYSTEM Overview:
- The Sentinel (ICU) has been borne out of more than 20 years of development of adsorbents for the processing of transformer oils. This enabled the development of an adsorbent that not only dries the transformer oil, but also removes acidity, dissolved sludge and the other polar compounds that are present in aged transformer oil.
- This experience led to the design and introduction of the Sentinel (ICU) as the worlds first, and only, online, transformer insulation system conditioning unit, utilising this well proven and proprietary adsorbent technology. With now more than 130 Sentinel (ICU) systems in use in a number of countries and with more than a 18 months of analysis on some of these system to draw upon we are able to design and operate a comprehensive moisture management programme on behalf of our clients. From the outset, the desire was to produce a system that was; a) unaffected by the polar contaminants found in aged oils, b) cost effective, c) reliable and d) easy to install and operate.
- The next logical step was to combine the online drying and purifying solution with an online oil condition monitoring system to monitor the oil quality 24/7/365 to ensure the oil quality and the high voltage transformer operation identifying critical operation conditions, overloading to prevent damage to the assessment. The online monitoring system is called: OilQSens® OQ 3000 oil sensor system. The combination of both unique systems is titled: SmartSentry® system. Installation scheme and typical SmartSentry® transformer installations are shown in fig. 1 and fig. 2.

- RESULTS FROM COMPARISON TRIAL:
- A major utility ran a trial where two sister transformers were fitted with drying systems. One was a conventional Molecular sieve and the other the Sentinel (ICU). The graphs below show the performance of both systems over a 6-month period, with regard to a) moisture reduction and b) acidity.
Fig. 3: Comparison of a) the moisture reduction and b) the acidity over time with a standard molecular sieve and the superior SmartSentry® solution.
- INTERFACES:
- The SmartSentry online transformer oil cleaning solution and condition monitoring system can be adjusted to your needs, providing all kind of industrial digital interfaces (RS232, LAN, CAN, Profibus, …) to be implemented in your existing CMS environment or using the cmc Instruments CMS server. The system is easy to retrofit into existing high voltage transformers.
- BE PREPARED FOR INDUSTRY 4.0:
- The power industry is strongly working towards solutions for the technological advancements currently reshaping the industrial world: what is called Industry 4.0. Industry 4.0 is the fourth industrial revolution, where the brainpower that has gone into creating apps for smartphones is creating applications for smart factories (see figure 4).
