EMV-INspektor® V2

Fieldbus problems or EMC problems?

The increasing power density of the industrial production results in a higher risk of interference currents along the cables, on the conducting paths of the power supply and those of the potential equalization systems. The diagnostic tool EMV-INspektor^® V2 allows an automated, contactless and uninterrupted test and detects electromagnetic disturbances temporarily. Up to four current transformers can be connected to the device. The measurement values are recorded separately, evaluated and compared. The INspektor^® displays effective values, amplitudes and frequency components for each channel. The amplitudes and the spectrum are visualised over time in a diagram.

Capturing currents with up to 4 measuring adapters

Intelligent capture of sporadic interference peaks and emc interferences

Application example EMV-INspektor^® V2

On all four channels, the current course and the spectrum are captured. This makes it possible, for example, to detect if there is a link between PROFIBUS malfunctions and PE/PA currents. The additional frequency data from the spectrum provide clues regarding the possible cause of the fault. Frequency components in the lower kHz range point to pulse frequencies of frequency inverters.

Measurement approaches:

EM interferences along the BUS cables
EM interferences via the 24 VDC power supply
EM interferences via the 230/400 VAC lowvoltage distribution system
EM interferences in the equipotential bonding system
EM interferences via the transmitter lines

Measuring adapters:

1 measuring and diagnostic clamp included, up to 4 clamps connectable with the INspektor^®
Measuring range from 1 mA to 50 A AC
Measurement category 600 V CAT II, 300 V CAT III
Clamp aperture 30 mm
Lenght of the connection cable ca. 1.5 m

Intelligent capture of sporadic interference peaks - stationary or mobile

To analyse a current course, it is important to know the amplitudes of the current. With the EMCheck^® ISMZ I and the EMV-INspektor^® V2, currents can be scanned at 40 kHz or 50 kHz. For each scan point, you also obtain the amplitude in order to realise a meaningful analysis. The current data recorded in the devices can be easily accessed with the free EMCheck^® View software.
