A New Artificial Line For Testing High-Voltage Circuit Breakers

In a high-power laboratory, artificial lines are used for short-line fault testing on high-voltage circuit breakers. Over the years, several different configurations of artificial lines have been designed and used in testing laboratories. This article describes an artificial line for testing circuit breakers with current ratings up to 100 kArms. The artificial line combines constructional advantages with good practical results and has been successfully in use in KEMA's High-Power Laboratory since 1978.
