The Yokogawa EY200 Digital Earth Tester is an earth resistance tester for testing power distribution lines, in-house wiring system, electrical appliances etc. The Yokogawa EY-200 also has an earth voltage range for earth voltage measurement. A simplified 2-pole measuring method can be used if there is an almost perfectly earth/ground object such as a lead or iron water-pipe (plastic pipes cannot be used) or if there is an object with a known value of earth resistance, near the measurement site. The Yokogawa ey200 Digital Earth Tester is dust and drip resistant (IP54 rated)

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.
