6.9 Measuring
operating times for
under (current/
voltage/other entity)
relays
1.
Initial setting: OFF.
2.
Connect the relay current input and tripping
output to Sverker.
3.
Set the timer start condition to INT.
4.
Set the timer stop condition (to CLOSURE
+ OPENING, CONTACT for example).
5.
Activate ON using the start switch. Set the
entity (current or voltage) being tested so
that it exceeds by an ample margin the
value that has been preset for the relay.
6.
Activate OFF+TIME using the start switch.
7.
Read and note the time and current.
6.10 Measuring
voltage
1. Set the voltmeter to measure AC or DC (see
Chapter 6).
2. Connect the voltmeter input to the voltage
that is to be measured. Do not exceed the
voltmeter specifications.
Note!
To measure a voltage in the HOLD state,
you must simultaneously measure a
current (by short-circuiting the current
output with a wire for example).
