Advanced Relay Test Sets for Precise Electrical Testing

Arc flash protection systems are designed to detect arcs which occur during short-circuits in switchgear and to minimize the potential hazard to personnel and equipment by reducing the time of occurrence and disrupting the flow of energy feeding the arc flash. For testing such systems, the ARC 256x Arc Flash Initiator simulates an arc by a xenon tube, very similar to a camera flash. This CMC accessory is positioned close to the arc flash sensor during testing. Via its 6 m (19.7 ft) long connection cable it is connected to the external interface socket of the CMC test set, which provides both the supply voltage as well as the signal that will trigger the flash. Features: • It utilises a xenon flash tube to simulate arc flashes accurately for testing purposes. • It comes equipped with a 6-metre (19.7 ft) cable to connect to the external interface socket of the CMC test set, providing flexibility during testing. • The device is powered directly from the CMC test instrument, eliminating the need for additional power sources. • It’s compatible with various CMC test sets, including CMC 356, CMC 353 and CMC 256plus. • It boasts a compact design with dimensions of 40 x 20 x 80 mm and a weight of 215g, making it easy to transport and handle during testing. -
The CMC 256plus is the first choice for applications requiring very high accuracy. This unit is not only an excellent test set for protection devices of all kinds but also a universal calibrator. Its high precision allows the calibration of a wide range of measuring devices, including: energy meters of class 0.2, measuring transducers, power quality measurement devices and phasor measurement units (PMU). Its unique accuracy and flexibility make the CMC 256plus ideal for protection and measurement equipment manufacturers for research and development, production and type testing. Features: • Protection test set and universal calibrator in one device • Testing of all relay generations – electromechanical, static, numerical, IEC 61850 • Highly accurate test signals. For meter testing: The sources are the reference – no additional reference meters are required • Integrated network for testing IEC 61850 IEDs • 10-channel analog measurement and transient recording functionality

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set. Features: • Powerful current sources for testing even high-burden electromechanical relays • High accuracy and versatility for testing static and numerical relays of all types • Integrated network for testing IEC 61850 IEDs • 10-channel analog measurement and transient recording functionality (option)
