Despite their reliable design, condition assessment of GIS is becoming more and more important as the average age of existing GIS systems moves towards the end of their life expectancy.

When measuring operating times and contact resistance on GIS with grounding on both sides, conventional testing methods such as dynamic resistance measurement (DRM) doesn’t deliver reliable results due to the low-ohm ground connections that run parallel to the circuit breaker. For this reason, measurements are often conducted with insulated grounding, or with grounding that is only on one side. However, this can cause capacitive coupling from adjacent components or switch bay sections on the non-grounded conductor and is a safety risk. CIBANO 500 offers a new, alternative method for measuring operating times in GIS – called the Current Sensor Measurement method, or CSM method for short. Additionally, a new technique called Grounded Contact Resistance (GCR) was introduced with CIBANO 500.

GCR combined with the CSM method for timing measurements on a GIS that is grounded on both sides allows users to accurately measure timing and contact resistance safely and accurately.

In this webinar, Mr Dongwon Lee will explain how precise and safe GIS timing and contact resistance measurement can be performed with CIBANO 500. He also will introduce the meaning and principle of CSM and how to analyze CSM result values.
