18 In-service diagnostic methods
This section describes in-service testing of circuit breakers with CIBANO 500 and its accessories.
Primary Test Manager in combination with CIBANO 500 supports the following in-service tests:
Timing (VTM)
First Trip
18.1 Timing (VTM) test
Note: To perform the Timing (VTM) test (VTM stands for Voltage-based Timing Measurement), you
need a license. Without the license, it is not possible to start the measurement and Primary Test
Manager displays a missing license message. To get the license, contact your regional OMICRON
service center.
