Got a power quality logger or analyser and not sure you're getting 100% from your instrument? Catch up on our easy-to-digest tips and tricks from the experts @Fluke.

Why does cable length between VFDs and motors matter?

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....

How a power facility reduced 40% of calibration time

Many facilities, such as power plants or production facilities, depend on a strong preventive maintenance program. These programs are essential to keep processes running safely and efficiently. Performing accurate and consistent pressure calibration on process instrumentation is an integral...

Five key test points to understand motor drive efficiency and performance

Motor drives are a well-known technology for transforming the constant voltage from the main ac power supply into a voltage that varies to control motor torque and speed ideal for motors that are driving mechanical equipment loads. Motor drives...

Keep those motors running: electric motor maintenance preventing downtime

Automotive customers have zero tolerance for bad parts and therefore, electric motor maintenance needs utmost care. One of our customers, CNP Myszkow, coats small parts for the automotive industry. After dip spin painting, they heat-treat the parts in a...

Find problems early by monitoring motor and drive efficiency

More than 40% of industrial motors work at or below 40% of their load rating. That means poor power factor and inefficient operation. Efficiency of all motors can drop over their lifetime, which increases energy and maintenance costs and...

The surest way to diagnose high-voltage surge arresters

Surge arresters play a key role in protecting electrical devices and equipment in high-voltage electrical substations. Like other devices, they must be periodically diagnosed. The most common method is visual inspection: checking that the arrester has no visible external...

How to find harmonics in electrical systems

Harmonics are currents or voltages with frequencies that are integer multiples of the fundamental power frequency. If the fundamental frequency is 60 Hz, then the 2nd harmonic is 120 Hz, the third is 180 Hz, etc. Harmonics are created...
