The Problem


Quality Energy detected harmonic interference 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 Solution

Quality Energy carried out a Power Quality Audit. Based on the data from the audit, our engineers and technicians determined that the ECG interference was coming from the main supply cable which carried a high level of third harmonic current. We recommended two 100 Amp Active Harmonic Filters, which were installed and programmed.
