Case Study: a medical clinic in Las Vegas, Nevada stops CT scan computer lockups with Dranetz power monitoring

a medical clinic in Las Vegas, Nevada stops CT scan lockups with Dranetz in 1 day

A medical clinic in Las Vegas was experiencing repeated computer lockups and component failures with its sensitive CT scan system. The clinic employed Dranetz power monitoring to analyze the power quality and identify the root cause of the problem.

Dranetz monitoring equipment identified the disturbance as severe transients caused by a nearby utility capacitor bank switching operation. Based on the data collected, which revealed a ringing frequency between 1 kHz and 1.5 kHz, an active-tracking filter was specified and installed on the 480-volt line. Dranetz data showed the filter successfully mitigated the transients, protecting the downstream CT scan equipment from further damage.
