Substantial savings at a printing press in Australia thanks to Merus™ Active Harmonic Filters
Challenges in the customer’s printing press
At the Belfast Telegraph, a large UPS feeding printing presses, IT and newsroom offices were suffering from non-linear loads that created voltage harmonic distortions as high as 8.6 %. Distortions this high cannot be tolerated as they can harm electrical equipment in a number of ways.
As the facility was risking a UPS failure, the customer decided to purchase a new UPS. The supplier, however, could not guarantee future operation of the UPS with such elevated levels of voltage distortion. Nuisance tripping was a permanent threat to vital data in the IT and newsroom offices unprotected against harmonic distortions.
Solutions that we found for the customer
Merus Power supplied the customer with a low voltage Merus™ A-series Active Harmonic Filter through Philip J Alcorn & Co, the company’s distribution partner in Northern Ireland. Fast response and selective harmonic cancellation were they key product features and criteria for the solution.
A Merus™ Active Filter was installed parallel to the loads. Merus™ Active Filters are configurable to meet various customer requirements. Thanks to the modern touch screen human-machine-interface (HMI) configuration is simple and just a few clicks away.
Results and customer benefits
- smooth plant operation
- Longer equipment service life
- Optimized plant operating costs
- No harmonic distortions or load unbalance
The effective and fast responding Merus™ A-series Active Harmonic Filter ensures that the Belfast Telegraph facility is now running smoothly. Harmonic distortions were brought down significantly and are now well below the requirements of G5/4.
Threat to important data was deterred by the installation of a Merus™ A-series Active Harmonic Filter. Harmonic mitigation maximized the UPS service life and resulted in smooth operation.
