TAVRIDA ELECTRIC - Manufacturer and global supplier of medium voltage electrical switchgear equipment

Tavrida Electric has revolutionised circuit breaker design by developing a new generation of circuit breakers and controls with exceptionally fast opening, closing and response times. Opening and closing times are as low as 12 and 24 ms, respectively. This enables Fast transfer switches with transfer times as fast as 2 cycles. Such quick operational times allows very sensitive loads to operate without interruption in case of a main power source loss. The fast transfer switch solution eliminates costly downtime, reduces production equipment stress, ensures quick return on investment. Arc flash mitigation with interruption in one period. That quick interruption time increases operational safety, reduces switchgear restoration time and loss of productivity, limits switchgear damage and repair costs. Fault current limiting solutions without operational losses capable to automatically reconnect power sources.

Tavrida Electric's circuit breakers are the perfect match for applications like transformers or generators with a neutral earthing, server rooms and point on wave switching. The circuit breakers weigh less than 14 kg, meaning they can be installed quickly and cost effectively in even the smallest of spaces.

Tavrida Electric manufactures small, compact vacuum interrupters with an extraordinarily long mechanical and electrical lifespan. A specially designed axial magnetic field distribution provides an even current density over the contact surface, substantially improving the vacuum interrupting performance. Vacuum interrupter contacts have unique design, based on the mixture of copper and chromium metals and various dopants, to ensure long electrical life of contacts, low contacts resistance and chopping current. The patented, supercompact actuator design allows the circuit breaker to be installed directly underneath each pole. The design is optimal in terms of reliability, dimensions, weight and ease of installation. A spring charged by the magnetic actuator during the closing of the circuit breaker ensures main contacts pressure is maintained. The spring is integrated in the actuator and does not require any maintenance during the circuit breaker's lifetime.

Continuous selfsupervision. Vacuum circuit breakers equipped with the CM16 control module continuously monitors control, switching modules, functional wiring and auxiliary power supply quality. CM16 eliminates the necessity of additional trip and close coils, charging mechanisms and all related wiring supervision. The whole trip and close circuit supervision comes in single package with any Tavrida Electric VCB. CM16 allows the user to forget about scheduled trip and close wiring inspections as in the event of malfunction corresponding notification will be sent to the operator using one of the inbuilt output relays and indicated by inbuilt in CM LEDs. Low power consumption. Vacuum circuit breakers equipped with the CM16 control module need less than 42 W in charging mode – just 10% of what the best alternatives available on the market need!

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.
