Good insulation resistance in a metal sheathed platinum resistance thermometer (PRT) probe is important for obtaining accurate and stable temperature measurements. If a probe is cycled frequently between hot and cold temperatures, its components become fatigued over time, and moisture can leak through the sheath seal at the probe handle. This is a common cause of decreased insulation resistance and noisy measurements.Cold temperatures allow moisture to leak through the sheath seal into the probe’s...

It is an undeniable fact that frequency inverters provide the most benefits of the many methods of controlling induction electric motors. However, in some cases the use of a frequency inverter can have a negative effect on the motor. One of the causes of damage to electric motors due to the inverter effect, happens when the power cable between these two devices is too long. But why?The output of the frequency inverter is characterized by a PWM signal (Figure 2). Considering this signal, we will observe...

With all Power Meters, Power Quality Analyzers, Energy Loggers or Power Loggers you can measure quite a number of Power parameters. In fact, the number of variables these instruments can measure, log and store is in many cases overwhelming. Imagine yourself setting up, downloading and analyzing a 32GB file with a logging of 500+ parameters over a month period…..So, wishing for “I want to log everything” is in most cases not the best idea, and certainly not the most efficient way. This leaves...

Flickering lights can have an adverse effect on health, causing fatigue, lack of concentration, migraines and in some cases, epileptic shock. The severity of reaction and sensitivity varies from person to person. Some people can see a higher rate of flickering light than others. Fluorescent lamps can occasionally develop a fault that can cause them to have noticeable flicker.While health effects are a main concern, the production line of an industrial plant can also be affected. Workers can feel...

Grid connected photovoltaic systems are growing in importance as sustainable energy sources.The DC power of the solar panels is converted into an AC power by inverters. These are transformerless and, besides generating AC current, also inject a small DC Current. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime. For measuring these DC components, we need a Power Quality Analyzer...

What is IEC 61000-4-30 standard?The IEC 61000-4-30 standard ensures that the measurement results from Power Quality analyzers and loggers of different makes and models match up; so measurement results are comparable without any doubts. This is extremely important, especially when there is a dispute about supply voltage quality between different parties going on. To comply with this standard, the instruments should measure and evaluate in exactly the same way. The standard covers PQ phenomena like...

Intermittent faults are notoriously hard to find. If you don’t know when they’ll occur, you need some form of data logging. But to track them down they have to be correlated to the events that cause them. You may also need to transfer the data remotely. So, measuring instruments should be versatile and intelligent with a wifi connection, and may need to read two external sensors. Overhead and underground utility cables One of our customers is an energy utility with extensive overhead and underground...
