  • Power supply for reliable operation

    The situation:

    More and more systems are controlled by frequency inverters, high-performance power-controlled drives, pumps or air conditioners that cause commutation dips. UPS systems working well below capacity create new challenges for operators of high-availability infrastructures. We know that exceeding standardized limits on the one hand and a lack of suitable limits in the relevant frequency ranges on the other pose a considerable risk.
    This translates unexpectedly into massive interference, which often leads to costly troubleshooting in large-scale installations since it is not assumed to have been caused by the power supply. On the contrary, interference manifests itself, for example, in the IT or ICA (instrumentation, control and automation) terminals installed in data centers despite or indeed because of the fact that they are powered by UPS systems. This also results in lengthy warranty discussions with the manufacturers of faulty or ruined equipment.

    Our solution:

    The GHMT Power Quality Assessment examines the power supply quality independently of the manufacturer and identifies latent potential for impairment. We use top-quality calibrated test instruments to record the current network setup at pre-defined test points. Our engineers assess power supply parameters such as harmonics, voltage fluctuations, frequency stability, transients, commutation dips and flicker beyond the currently standardized frequency range to offer a reliable insight into the true quality of the power supply.

    Your added value:

    The GHMT Power Quality Assessment will identify equipment that causes harmonics and put forward optimization and corrective measures. This in turn will: counteract specific failures early on, increase the service life of devices and installations due to lower loads, increase the energy efficiency of your installation, cut investment costs, reduce operating costs and ensure a higher level of availability. In short, it is a very compelling argument.
