Network operator - Import export

Challenge To execute a pilot project at the Energisa distribution network operator in Brazil within a tight time frame. The customer needed to install 23 kV outdoor circuit breakers with protection at a newly erected substation. Solution Tavrida Electric supplied the Rec25 with substation mounting kit to meet the deadline and satisfy the customer’s requirements in terms of protection. The mounting kit was subjected to comprehensive mechanical tests including overweighting, wind load and seismic impact with successful results.

Thousands of nodding donkey oil pumps were energized through an extensive and highly meshed overhead electrical network. Automated protection was performed only by the feeder CB at the substation. None of the line sectioning breakers were automated, so every single failure on the network required human intervention and led to significant outages. Solution Tavrida Electric installed and commissioned six Rec15 with Rezip* functionality on a single line in just one day. The following project outcomes were achieved Direct savings (outage time reduction → revenue loss reduction) Indirect savings (operation, maintenance, and repair cost reduction) Improvement of power supply quality and reliability Drastically improved network visibility and operator awareness *Rezip is an advanced Fault Detection, Isolation and Restoration (FDIR) algorithm

Sophisticated control and protection Tavrida Electric reclosers provide protection from various faults, including short circuits, earth faults, high impedance earth faults, broken wires, islanding, incorrect tap changer operations, network overload and over or undergeneration. Embedded RTU and metering ensures the reclosers are SCADAready with no additional expenses. TELARM® Dispatcher and DualSCADA TELARM® Dispatcher is proprietary remote control and monitoring system that works as a standalone SCADA and/or in parallel with an existing SCADA system, acting as a backup method of controlling and monitoring reclosers. TELARM® Dispatcher offers a number of features not available with most conventional SCADA systems, such as remote access to system logs, fault and load profiles and the remote control of protection settings. With maintenancefree design rated to perform 30,000 open and close operations, Tavrida Electric reclosers keep expenses to a minimum over their entire lifespan.

Electrostatics disturb almost all production processes. Eltex systems prevent uncontrolled discharges and integrate electrostatics precisely into your processes. In our electrostatic discharge product portfolio, you will discover systems and products for many industrial sectors. All Components such as power supply units, output stages and module technology are integrated into the lean electrode profile of the new Smart Discharging System SDS. This system’s communication with machine/operator networks or operation via mobile end devices is particularly smart. The Smart Discharging System SDS is ideal for discharging in the middle distance and speed range for applications in automation technology and in the plastics and packaging industry.
