Thermal imaging batteries
Thermal imaging locates hot spots by examining the IR spectrum. Heat is the enemy of batteries.  A riseof just10°C willdeplete the lifeof a batteryby half. As molecules heat up,they move faster. This increases the rate of chemical reactions. This will increase the rate of oxidation that leads to corrosion. It will also increase the rate ofdry out in VRLA batteries. Heating will reduce the life of any battery regardless of the chemistry.

TTRU3 Factory ratio testing of power transformer
Transformer equipment manufacturers (OEMs) have a critical need to measure true ratio, as they must confirm proper manufacture of their transformers during construction and final assembly. Improper construction has consequences of higher cost, late delivery, and poor quality. The ability of a ratio instrument to be used for all steps involved makes it a practical valueto OEMs because only one instrument is purchased and used throughout each stage. Only the most reliable and accurate instruments make it to the factory floor. Winding stack under constructionre used: Art Mandigo Winding Service.

Testing frequency relays with SVERKER900 considering the IEC 60255-181 standard
This application note is more than a description of how to use SVERKER 900 for testing frequency relays. It also wantsto spread the knowledge about IEC standardization in relay protection. Many engineers often associate theIEC series of protection standards IEC 60255-1xx1to relay type testing, and believe that they do not need to have competence about this series of standards. This is a misunderstanding: many of the concepts, definitions and test procedures described in thestandards are there to be used in relay technique, no matter if the role is relay manufacturer, user, or commissioning / maintenance testing engineer ([2], [3]).

DLRO2: long test lead test mode
When measuring very low resistance the four-wire test method has for many years been the standard method. The main advantage being that it simply and easily removes the resistance of the test leads from the measurement. However, what happens when those test leads need to be verylong?

DLRO2: new difference meter
Introducing the first low resistance ohmmeter to feature a difference meter, a device that turns changes in resistance into a moving pointer and percentage change. When testing multiple similar connections, it makes it easy to spot those small increases in resistance that eventually turn into major faults.
