Predictive Maintenance (PdM)Power Test Equipment & DiagnosticsSafety Tools & Protection
High voltage oscillographic reflectometer Iskra-3M is designed for precise cable fault prelocation. Without this the knowledge of the fault point is not or only limited known. A good pre-location can determine the fault position within a few percent of the cable length. Resulting the boundaries of the fault are set, and the required time for the pinpointing is reduced to a few minutes. This saves working time, and keeps the stress level for the cable and its armatures low. Established only in 2005, DET (DneproEnergoTechnologii Ltd) already achieved significant results in manufacturing high voltage, high current testing and measuring equipment, equipment for cable fault location, insulating liquids testers for years, becoming a regional leader. Their clients are: energy generation and distribution companies, power plants, power utility companies and substations. Company DneproEnergoTechnologii (DET) practices individual approach to each client, dealer, representative and partner. They are in professional relationships with all their customers due to close cooperation and responsible approach to business. During the years DET accumulated vast experience in production many kinds of equipment for customers from Europe, Asia and Africa.
