Safety notes and notes for using Quick Test

WARNING
Death or severe injury caused by high voltage or current possible
For VT ratio measurement, the CT Analyzer output has to be connected to the primary
side of the VT. Connecting the CT Analyzer output to the secondary side of the VT by
mistake will cause hazardous voltages on the primary side.
► For VT ratio measurements using Quick Test, always make sure to connect the
CT Analyzer output to the primary side of the VT.
WARNING
Death or severe injury caused by high voltage or current possible
Using the DC current mode of the Advanced measurement type may be very
dangerous. In this mode, it is not possible to interrupt the circuit using a standard relay or
a standard circuit breaker. Due to the arc, contact clearances of up to 10 mm are
required to switch off the current.
► Do not use a standard relay or a standard circuit breaker to interrupt the current in this
mode.
► Always use a switching device with a sufficient contact clearance of > 10 mm to
interrupt the current or stop the current output on CT Analyzer.
WARNING
Death or severe injury caused by high voltage or current possible
Feeding an inductance with DC current will charge the inductance. CT Analyzer does not
perform automatic discharge of the inductance after measurements with Quick Test.
► Wait until the inductance has discharged completely before touching any connections
or disconnecting the measurement leads of CT Analyzer.
NOTICE
Equipment damage possible
When using Quick Test, the input SEC of CT Analyzer is able to measure voltages up to 150 V
► Do not connect voltages above 150 V or even mains voltage to the CT Analyzer inputs! This will
damage CT Analyzer.
NOTICE
CT saturation possible
When performing measurements on CTs using Quick Test, consider that CT Analyzer does not
perform automatic demagnetization of the CT.
► If necessary, run a normal CT test with its automatic demagnetizing cycle following Quick Test
measurements for a CT.
