Austrian OMICRON CMC 256plus relay protection test setSolutions:
•Relay protection testing
For the safe and reliable operation of today's power systems, relay protection systems play an important role. The normal operation of protection equipment helps maintain the safe operation of the power system and protects equipment from damage. To ensure reliable operation, relays and reclosing controllers must be tested throughout their entire service life, from initial development to manufacturing and commissioning, as well as regular maintenance during operation.
For all these phases in the life cycle and in any environment, our test equipment is a very ideal tool. As a reliable long-term partner, we provide users with test solutions for new technologies and continuously maintain and develop them, enabling users to meet the increasingly complex requirements of the system.
•Measurement equipment testing
The functional and accuracy testing of power system measurement equipment is either required by mandatory standards or regulations, or is part of existing quality assurance concepts. For various types of measurement equipment, such as power quality measurement devices, energy meters, or transmitters, valid measurement values can only be provided after proper calibration. Calibration is carried out during the development process, type testing, and commissioning. At all stages of these processes, system operators must regularly test them to ensure reliability. For all these application areas, we can provide multifunctional, portable, high-accuracy test solutions.
•Power system automation communication
IEC 61850 is the international standard for communication between devices in substations, defining communication between intelligent electronic devices (IEDs). This standard defines a common data model for IED devices and the complete engineering process. The IEC 61850 standard has had a significant impact in the field of relay protection engineering, and a large number of operating substations have adopted this standard. From the very beginning, major relay manufacturers worldwide have used our equipment to perform performance testing of IEC 61850 devices and to demonstrate device interoperability. In this field, we have always maintained a leading position, providing a wide range of advanced IEC 61850 test tools for relay protection engineers in substations or laboratories.
Austrian OMICRON CMC 256plus relay protection test setAccessories:
•ARC 256x arc flash initiator
Used to detect arcs that occur during short circuits in switchgear
Arc flash protection systems are designed to detect arcs that occur during short circuits in switchgear, shorten the duration of the arc, and cut off the energy source of the arc to reduce potential harm to personnel and equipment.
To test such protection, the ARC 256x arc flash initiator simulates an arc using a xenon tube, very similar to a camera flash. During testing, this CMC accessory is placed near the arc flash sensor. It is connected to the external interface socket of the CMC test instrument via a 6m (19.7 ft) cable, which provides both voltage and trigger signal.
•C-Shunt precision shunt
Precision shunt for measuring current
C-Shunt1 and C-Shunt10 are precision shunts for measuring current. They can be directly plugged into the binary/analog input interface of OMICRON test instruments (such as CMC or COMPANO 100).
•CMC wiring accessory kit
Optional wiring accessories to connect test objects to the CMC test instrument
The CMC wiring accessory kit includes:
12 flexible test lead adapters with retractable sleeves, very useful for connecting to non-safe banana jacks, fully compliant with IEC 61010-031 safety standard. (100 mm long, 6 red and 6 black)
4 flexible jumpers (50 mm long) for paralleling current outputs up to max 32 A, or for shorting the midpoint of binary inputs (50 mm long)
8 alligator clips (4 red, 4 black)
12 flexible terminal adapters for screw-type terminals
20 cable lug adapters, M4 (0.15") screws
10 cable lug adapters M5 (0.2") screws
