Autorecloser (REC)

Tavrida has combined their innovative vacuum circuit breaker technology with a novel recloser control that is unrivalled in reliability and ease of control. Available in both 15 and 27 kV, the OSM series are easily the most lightweight and compact reclosers available on the market. Unequalled in features to control your network, Tavrida recloser systems can be used for ring or radial configurations, offering full back-feed restoration and sectionalizing capability. The Autorecloser provides the following advantages:

Directional over-current protection
Directional earth-fault protection
Directional sensitive earth fault protection
Under-voltage protection
Cold load pickup
Inrush restraint
Voltage reclosing control which allows the customer to program loop automation functionality
Separate event logs for close open operations & fault protection operations
Instantaneous voltage, current and power metering
Load profile data
DNP3 and Modbus protocols
Programmable digital inputs/outputs

TELARM software package

	The REC/TEL series autorecloser is designed to work with Tavrida’s recloser software. TELARM (Tavrida Electric Automated Relay Manager) is presented by two software packages – TELARM-Basic and TELARM-Premium.

	TELARM-Basic is a comprehensive recloser configuration and control tool. It provides all functionality required for recloser set-up, management and maintenance.

	TELARM-Premium has been designed to eliminate the extraordinary complexity of calculating and testing of optimal recloser settings. Additionally to TELARM-Basic features it includes tools for grid modeling, off-line recloser settings calculation and testing.
