Equipotential bonding analysis: Detecting hidden sources of interference
EMC measurement: making the right decisions
– Reliable detection of interference sources
In modern industrial plants, switched-mode power supplies, drive solutions or frequency converters influence the load status of your equipotential bonding system. These correlations cannot be determined with conventional RMS current measuring instruments. For this reason, precise EMC measurement is not as trivial as it may appear at first glance.
For illustration: More and more drives are RPM-controlled. The connected frequency inverters lead to higher-frequency operating currents. These result in strong, changing magnetic fields which, for example, lead to an undesired shielding current on the bus cable. Conventional current clamps cannot identify the cause. Thus, the EMC interference source would first remain undetected.

In short: 6 things that make our professional EMC measuring tools unique
Smart long-term monitoring instead of punctual measurement
Due to complex correlations in modern industrial plants, many EMC interference factors only become visible during long-term measurements. These remain slightly undiscovered during selective measurements.
Conventional EMC measuring devices usually measure selectively and are only a snapshot. This serves primarily to determine the basic quality of your equipotential bonding at a certain point of time.
Reveal sporadic, non-reproducible incidents
Unlike common current clamps, EMCheck® ISMZ I and EMV-INspektor® V2 have a long-term measuring function. Thanks to the continuous measurement and recording of currents, sporadic interference peaks become visible. Especially sudden interference impulses, such as a switching action on the contactor, cannot be detected by conventional current clamps.
Understanding EMC correlations without additional special equipment
Measure at up to four measuring points simultaneously with the EMV-INspektor® V2. Thanks to the parallel data recording of different measuring channels, specific correlations and interactions can be identified. This enables you, for example, to correlate errors on the fieldbus with PE/PA currents.
Identifying interference causes - using frequency analysis
In addition to the current curve, also the frequency spectrum of the current is evaluated. On the basis of the information about the frequencies, you can draw conclusions about possible sources. Expert hint: Currents in the kHz range require other steps to improve equipotential bonding than, for example, 50 Hz currents.
Non-contact and interruption-free EMC monitoring
All our EMC measuring devices can be installed and used during operation. The large clamp heads fit over all common plant and industrial network cables. This ensures the greatest possible flexibility and applicability.
