Portable switchgear test system with up to 16 analog and 36 binary measurement inputs

ACTAS P22 is a high-precision, portable measuring system which has been specially developed for operating tests on various types of switchgear device, including circuit breakers, disconnectors and earthing switches, regardless of the type of drive unit. All the electrical and mechanical parameters needed for the assessment of switching performance are measured in real time without either the main contact chamber or the drive unit having to be opened. 26 inputs are provided for measuring analog and incremental signals. 14 inputs can be used simultaneously. A total of 36 binary measurement channels enable measurements to be made on 18 auxiliary contacts and 18 main contact chambers (6 per pole).  With three-phase control of the operating coils, ACTAS P 22 can be used to test all medium- and high-voltage breakers.

In addition to the usual analysis made on the basis of the binary switching status, operating times can also be determined with the Dynamic Timing function. Using this special method which is particularly well suited to measurements on graphite contacts, the contact status of up to 3 x 2 main contact chambers can be determined simultaneously by means of a dynamic voltage drop measurement. An additional advantage of this method is that the breaker can remain earthed on both sides during the measurement. In addition to the standard equipment, the P22 dyn device option includes six constant current sources (10 A) and six measurement inputs for voltage drop measurements.
