In this day and age, reliability in electrical supply is imperative to a great extent. However, one of the critical areas in sustaining that reliability is the stability, reliability, and quality of the voltage supply. This is where the Voltage Dips and Interruptions Test comes into play as an invaluable power quality measuring tool. It is paramount for evaluating how quickly and how electrical equipment will respond during unexpected voltage supply dips, or complete losses of voltage supply, also known as consumer interruptions, in real time.
