Due to their quality, reliability and design, these relays are optimal for applications requiring high reliability and availability such as power stations, substations, railway and industrial plants. Typical examples include petrochemical industry, chemical industry, cement industry, rolling mills etc. The relays comply with the IEC, EN, IEEE standards (type and routine test) and bear the CE mark. The robust switch contacts are characterized by high make/break capacity, overload capability and continuous current intensity capacity; thus perfect insulation is obtained. Direct control of high-voltage and medium-voltage switchgear is possible. Their high degree of protection and the transparent cover ensure reliable operation in tropical and/or salty sea air ambient conditions.
Light-weight and compact the 7VP158 is the most powerful solution in the field of secondary injection testing. The 7VP158 has been designed to provide a solution for every eventuality. Distance protection, overcurrent protection and differential protection equipment as well as monitoring relays, synchronizing devices, energy meters and measuring transducers can be tested using 7VP158 test unit. The 7VP158 offers a wider range of features than the 7VP151.
