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


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


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


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


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


Example: Undervoltage release
