The VLF sine wave 45 kV with integrated tanDelta is a compact, robust, and portable high-performance test and diagnostic system for medium voltage cables. The 45 kV tester is a multifunctional tool: apart from VLF and DC testing, it also performs sheath testing and sheath fault pinpointing (in combination with the step voltage probe ESG NT). Moreover, the optional internal tanDelta expands the system to assess both cable integrity and condition.

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.
