The Problem

Harmonic interference was detected in close proximity to the ECG equipment in the new outpatient’s wing. This interference put the ECG test results into question and caused the ECG test area to be temporarily closed.


The Consequences

Part of the hospital and an important patient service was closed.


Our Solution

Initially, we carried out a power quality audit. We found that the ECG interference was coming from the main supply cable which carried a high level of third harmonic current. 2 x 100 amp Active Harmonic Filters were installed and programmed to eliminate the third harmonic pollution.


The Benefits

The hospital was able to reopen the ECG test area and continue its important, lifesaving work.
