ACTAS P

System description

The automatic test systems of the ACTAS product range can determine and check the major electrical and mechanical parameters of all types of breakers. The universal modular concept behind the ACTAS systems enables us to provide exactly the right system for any specific application, from portable starter devices through to professional solutions for fully automated final factory tests. The voltage level and design of the primary and drive circuits are irrelevant as ACTAS systems are fully equipped to deal with all types of breakers.

An important feature of all ACTAS systems is the combination of robust hardware capable of real-time processing with the manifold possibilities afforded by convenient, PC-based software. Configuration, display and analysis are fully PC-supported. All test steps can thus be carried out from a dry, safe location enabling you to escape the adverse environmental conditions often encountered on site. The option of an integral industrial PC is also available for various models.

ACTAS test systems are constructed according to a modular design in 19" format and are based on the latest 32/128 bit DSP processor technology. All measurement inputs are, of course, galvanically separated from the input terminals. KoCoS LOC circuits (linear opto-couplers) are used for the analog channels guaranteeing very high levels of accuracy and an absolutely linear frequency response characteristic as well as trouble-free operation even in harsh electro-magnetic environments.

Circuit breaker tests are usually performed dynamically using various sequences of operations with simultaneous capture of the relevant measured values in the drive and primary circuits. All parameters are then automatically calculated and checked on the basis of the measured values.

The ACTAS product range offers a wide variety of different models and extension modules for specialist test situations. The Dynamic Timing option, for example, makes it possible to determine the contact times of breakers which are earthed at both sides by means of dynamic voltage drop measurement. All systems have control outputs for external modules for the purposes of static or dynamic determination of main contact resistances.
