ES-CAV and ES-OSM prefabricated compact substations are manufactured and tested according to the standard IEC 62271-202:2014 requirements. The ES-OSM metal enclosure compact substation can be equipped with different type medium voltage ring main units, as well ES-SLV type low voltage switchgears with different configurations. The ES-CAV concrete enclosure compact substation can be equipped with different type medium voltage ring main units and secondary distribution switchgears, as well low voltage switchgears
with different configurations and medium voltage measuring chambers. The ES-OSM metal enclosure compact substation can be equipped with different type medium voltage ring main units, as well ES-SLV type low voltage switchgears with different configurations.

ES series complete state-of-the-art switchgear. ES-series complete high-end switchgear. The design of the switchgear has been developed by Eltech Solutions OÜ to fulfill various technical solutions, which many standard solutions do not allow. The main advantages of the construction are the rigidity of the main structure of the frame and the flexibility based on modularity (perforation in 25 mm increments). Switchgear complies with the requirements of EN 61439-2, EN 61439-1 and EN 60947-1

In addition to the sales of Medium Voltage switchgear we can also design control, signalling and auxilliary circuits for MV switchgear. We also provide 3rd party FAT tests in manufacturer’s permises or FAT in our facility depending on the project. We also provide third party service work at the FAT manufacturing plant and on-site FAT at the Eltech Solutions OÜ plant.

We have a wide range of configuration experience with various RTU manufacturers therefore we are also able to provide configuration and commissioning services in addition to the products in our portfolio.

We have wide experience in the field of configuration and commissioning works with different manufacturer’s equipment such as Schneider Electic: P3, Vamp, Micom, Saitel; ABB: REx, RTU5x0; A-Eberle EOR-D, Reg-A1:C208 Reg-DP; Kries Energietechnik IKI; Meinberg Lantime; Moxa switches, converters; Siemens Logo!; Trench EFD and so on. For the testing of relay protection we can use Omicron CMC356, Compano and other manufacturers testing devices.

Power transformers (ONAN, ONAF), distribution transformers (oil, dry, cast-insulated), special application transformers (auxiliary transformers, converters, reactors, petersen coils), measurement transformers for medium voltage applications.
