22.5 Current sensor
22.5.1 Designated use
The current sensor is used to measure the operating times on both-side grounded gas insulated
switchgears (GIS) with grounding switches. During the dedicated Timing (CSM) test (see 17.3.5 "Timing
(CSM) test" on page 226) the sensor detects the change of current flow through the measured ground
connection of the grounding switch. The current sensor is only intended to be used with the CIBANO 500
test system.
