The applications of circuit breaker test systems
Development:
Stationary or portable test systems
Type test:
Stationary or portable test systems
Final inspection in the series production :
Stationary test systems
Revision tests:
Portable test systems
KoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
The test system types for these applications
Recording and calculation of all important
timing, travel, voltage and current results of
any operation
Controlled output to all releases
Supply different voltages for the releases
KoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
The requirements to circuit breaker test systems
Providing of necessary actuator voltages to
test the trip behaviors with minimal, nominal
and maximum voltages
Set drive pressures
Clamping spring drives
Monitoring and automatic set of the switch
position for a testKoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
Automation before a test
Several different power sources can be controlled
and adjusted automatically during the test with
ACTAS
Many power sources have an analogue 0 to 10
VDC control input, and thus the possibility to
output a voltage between 0 to 300 V
Other power sources are equipped with a data
interface (serial or IEEE488/GPIB) to set the
voltage via commandKoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
Power sources
Motor / Drive
Opening and closing coils
Undervoltage release
Overcurrent release
Blocking magnet
KoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
Power sources – For which functionality
Medium voltage breakers
Output of ramps with power sources, e.g. for
testing of the behavior of undervoltage
releases
Valve-controlled pressure ramps for testing
density monitors / alarm contacts
Continuous switching for life cycle test

Automation during a test
Automatic increase or decrease
of the voltage of a power
sources
Step width and voltage
difference are free to enter
Any trigger possibilities for
start and end of the ramp
KoCoS – MESSTECHNIK AG | Geschäftsfelder | Mess- & Prüfsysteme für die Energietechnik | Schaltgeräteprüfung
Ramps
Starting at rated voltage
the power source is
regulated slow down
The ramp stops with the
opening of the main
contact
The system determines
the trigger voltage
