Testblock
Standardized Test Access, Isolation and Circuit Handling
ODES TESTBLOCK provides standardized test access, isolation, and circuit handling for protective relaying and secondary circuits. Designed for commissioning, periodic testing, metering verification, fault recorder testing, and maintenance, it supports CT automatic shorting, PT test isolation, and safe isolation of trip, signal, auxiliary power, and control circuits.
Product Capabilities
Modularize test access, isolation, and circuit handling for protective relaying.
Protective Relay Test Access
Provides fixed test interfaces for protective relay testing, metering verification, fault recorder testing, and control circuit maintenance.
CT / PT Circuit Handling
Supports automatic CT shorting, PT test isolation, make-before-break switching, and controlled isolation paths.
Trip, Signal, and Control Circuit Isolation
Provides test isolation for trip, signal, auxiliary power, and control circuits, reducing the risks of unintended operation and wiring disturbance.
Test Handles and Accessories
Supports matching test plugs, test handles, operating covers, labels, and project-specific spare parts.
Customer Value
Make field testing faster, safer, and more repeatable.
Faster Testing
Fixed test interfaces and matching test handles reduce temporary wiring, verification steps, and restoration time.
Safer and More Reliable Circuits
Clear isolation paths are maintained throughout testing, helping reduce the risks of CT open circuits and unintended operation.
Reusable Modules
Test modules, test handles, and accessories are designed for repeated use throughout long-term operation, maintenance, and testing.
Reduced Field Testing Complexity
Complex test access and circuit handling are standardized into modular solutions, reducing reliance on individual field-testing experience.
Shorter Test Cycles
Standardized, modular, and reusable test access helps shorten commissioning, maintenance, and periodic testing cycles.
Product Series
Configure product series according to customer operating and configuration preferences.
Switch-Handle Interface
TSBA Switch-Handle Test Module
Designed for protection, metering, control, and instrumentation secondary-circuit testing applications that require front-panel-visible switch handles, color identification, position numbering, and individual circuit operation.
Plug-In Interface
TSBE Plug-In Test Module
Designed for applications using fixed test modules together with matching test handles or test plugs, enabling circuit isolation, automatic CT shorting, and test access through plug-in operation.
Test Plugs & Accessories
Test Plugs & Accessories
Includes FTE / FTA test handles, test plugs, protective covers, labels, handle identification, spare parts, and project-specific auxiliary components.
Replacement & Selection Support
Replacement & Selection Support
When customers are replacing an existing brand or only have a model number, product photo, BOM, or project technical specification available, ODES can assist in identifying the appropriate TSBA, TSBE, or customized configuration.
