Measure Resistance in a Circuit Breaker
Developed as an extension for the ACTAS C switchgear testing systems, it combines maximum measurement accuracy with integration into automated test sequences. The PROMET CE delivers constant test currents of up to 200 A, enabling a precise measure of electrical resistance and reliable assessment of contact behavior under realistic conditions.

Resistance measurement integrated into switchgear testing systems
The PROMET CE is powered and controlled directly via the ACTAS system. This guarantees uncomplicated handling without additional control elements or power supplies. All test parameters are set in the ACTAS test software and the results are transferred to the test reports.

• Integration into ACTAS C switchgear testing systems
• Constant test currents up to 200 A for a precise measure of resistance and accurate evaluation of contact performance
• Parallel testing of up to 12 main contacts in a single pass
• Complete switchgear testing without reconnecting in one test sequence
• Automated test sequences with complete documentation in the ACTAS software
• High efficiency thanks to direct system power supply
• Precision for reliable results in the micro- and milliohm range

Areas of Application – Measure Resistance Under Realistic Conditions
With a variably adjustable test current of up to 200 A, PROMET CE covers a wide range of applications. The highly stable current source enables constant measurement conditions, so that even resistances in the micro- and milliohm range can be reliably measured, providing a highly accurate resistance measure for diagnostic purposes.
PROMET CE really shows its strength when used with dynamic switching tests: Contact resistances can be precisely measured and compared under realistic operating conditions. This is an essential basis for assessing the condition of modern switching devices.

Condition Assessment of Circuit Breakers by Measuring Contact Resistance
The accurate measurement of contact resistances is a key indicator of the condition of switchgear. PROMET CE can be used to detect critical changes in contact behavior.

Type Testing and Factory Acceptance Tests – Reliable Measure of Resistance Data
PROMET CE provides measurement data for type testing and final inspection at the factory during the development and production of switchgear. This ensures that all components meet quality and safety standards.
