Indoor Switching Modules (ISM)

   
Utilizing unique single-coil magnetic actuators and our own state of the art vacuum interrupters, these modules present the competitive solution for switchboard manufacturers. They can be applied with equal effectiveness in a wide variety of switchgear, be it newly developed or old, air or SF6 insulated, stationary or draw-out.

Indoor switching modules shall be installed in combination with control modules providing control and permanent monitoring of both modules. Our indoor switching modules give the user the following benefits:

    • Exceptional reliability
    • No maintenance needed during the entire lifetime
    • Long mechanical and interrupting lives
    • Flexible mounting and interlocking interface
    • The smallest dimensions and lightest weight available in the market


Control Modules (CM)

 
  
These microprocessor-based modules provide control and supervisory functions for indoor and outdoor switching modules. They are suitable for application in substations (different types are available for different auxiliary voltages and signaling interfaces). The following unique features of the control modules will provide your switchgear with new competitive advantages:

    • High reliability
    • No maintenance needed during the entire lifetime
    • Suitable auxiliary interface
    • Support of fast autoreclosing
    • Easy SCADA compatibility
    • Small dimensions and lightweight


Outdoor Switching Modules (OSM)

 
  
OSMs utilize indoor switching modules inside a dead tank, made of corrosion proof, powder coated aluminium. Three out of six bushings are equipped with built-in current transformers.

All OSMs use a unique patented solid insulation system. OSMs are designed for use as automatic circuit reclosers on overhead distribution lines as well as outdoor circuit breakers in distribution substation applications for voltages up to 27kV when installed together with the designated control module.

Like all TAVRIDA ELECTRIC products the OSM is the most advanced product of its kind in the market today:

    • Exceptional reliability
    • No maintenance needed during the entire lifetime
    • Exceptional long mechanical and interrupting lives
    • Smallest dimensions and lowest weight available in the market
    • Ability to fulfill fast autoreclosing


Autoreclosers OSM

 
  
 Tavrida Electric offers a new range of OSM vacuum autoreclosers based on the application of its own outdoor switching modules and recloser control cubicles. This autorecloser makes full use of the advantages of TEL outdoor switching modules enhanced with the application of a unique combined voltage and current sensor providing accurate measurements of six voltages and four currents (3 phase + residual). Recloser control cubicle uses powerful microprocessor to support protection and communication functionality suitable for radial and ring feeders for various types of neutral earthing:

    • Directional overcurrent protection
    • Directional earth fault protection
    • Directional sensitive earth fault protection
    • Undervoltage 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


ISM Based Draw Out Units

 
  
Tavrida Electric and its partners manufacture several types of draw out units based on the application of indoor switching and control modules.

Surge Arresters

 
  
Tavrida Electric manufactures a range of medium and high voltage surge arresters based on the unique technology of the encapsulation of zinc-oxide varistors into polymeric housing. This technology allows us to get rid of the residual air inside the surge arrester housing entirely. Together with the careful selection of sub-suppliers of varistors and encapsulating materials this technology provides our surge arresters with the following set of unique features:

    • Exceptional reliability
    • High heat dissipation capability
    • Resistance to internal arc
    • Small dimensions and lightweight

Tavrida Electric designs and manufactures all vital parts of the vacuum circuit breakers in-house. Extremely compact vacuum interrupters and magnetic actuators are the result of intensive fundamental research and material testing. Optimal selection of components and materials result in the lightest and most compact vacuum circuit breaker in the world today.

Our modular vacuum circuit breaker concept consists of the switching module ISM and the control module CM and both resemble the integral function of a conventional circuit breaker.

This has the advantages of being very compact and allowing flexible mounting positions.

The combination of vacuum switching technology with state-of-the-art magnetic actuators, driven by the separately mounted CM, guarantees maximum reliability and maintenance free operation throughout the entire 25 year lifespan.

The concept has been proven with more than 100 replacement solutions for old circuit breakers in various types of switchgears. Another successful application is outdoor switching modules. Combined with unique current and voltage sensors as well as a powerful protection and control package Tavrida Electric offers state of the art autorecloser.
