The Serveron® Model TM1 offers a breakthrough price/ performance point in on-line DGA. For the first time, the benefits of on-line condition monitoring can be realized across the distribution transformer fleet. The Serveron® TM1 continuously monitors and reports hydrogen PPM Levels and can be programmed to alarm based on PPM Levels and/or Rate of Change (ROC), warning operators of potentially disruptive transformer faults and pending failures.
