KoCoS Messtechnik AG products

Flexible and compact test systems for carrying out tests on medium-, high- and extra-high-voltage switchgear.

ACTAS BTT is a battery-operated, hand-held measuring device which can determine operating times, contact synchronicity, sequence time and coil currents extremely quickly and easily. Thanks to this extensive functionality and its high measurement accuracy, ACTAS BTT can be put to a wide range of different uses when measuring the operating times of low-, medium- and high-voltage switchgear devices, relay contacts, contactors and switch disconnectors, to mention but a few applications.

High-precision test system for function tests on various types of switchgear device, including circuit breakers, disconnectors or earthing switches, regardless of the type of drive unit. The inputs and outputs are connected flexibly via a terminal strip, making the test system particularly suitable for use in development and laboratory environments as well as in production environments.

PROMET SE is a compact, battery-operated ohm meter with an adjustable test current of up to 200 A. Two current outputs and two voltage measurement inputs allow the resistance to be determined at two measurement points simultaneously. Flexible handling with battery operation and the high functionality and precision which are characteristic of the popular PROMET product range make this universal micro-ohm meter particularly suitable for portable use in switching stations or industrial environments.

PROMET R300 and R600 high-accuracy, high-precision ohm meters deliver an adjustable test current of up to 600 A which is independent of the supply voltage. These measuring devices utilize the four-wire resistance measurement method, enabling them to meet the most stringent accuracy requirements. State-of-the-art power electronics coupled with a robust design guarantee excellent reliability for stationary and portable use in switching stations or industrial environments. PROMET ohm meters feature a modern operating concept, an interface to the test systems of the ACTAS product range and external control for use with test stands, making them both flexible and versatile.

More than 20 years of experience in developing and manufacturing automatic relay test systems have gone into creating the fourth generation of ARTES test instruments. Back in 1996, KoCoS was the first company to present Windows-based testing software for controlling and operating test equipment and the company continues to play a pioneering role in the design of clearly structured and ergonomic user interfaces today.

The measuring devices of the SHERLOG range combine the monitoring functions of a high-class digital fault recorder with the features of a power quality analyser in a single system. They can be used to comprehensively monitor power engineering equipment such as lines and bus bars and associated protection devices and switchgear equipment.
