Configuration and Performance of ODES ANSI-Type Test Switches
Beyond Safe Operation — What Defines a Good Test Switch In protection and control systems built to ANSI standards, performance is not just about “safe switching.” Engineers must also evaluate configuration flexibility, installation practicality, and environmental endurance . The TSBA Series ANSI-Type Test Switch from ODES was developed with these parameters in mind. It provides modular configuration options, robust electrical ratings, and accessories tailored for modern

ODES ANSI-Type Test Switches for Secondary Circuits
Re-engineering Safety in Relay Testing In ANSI-based protection systems, commissioning teams must achieve two goals simultaneously: guarantee zero CT open-circuit risk and complete isolation, measurement, and verification within limited panel space . A well-designed ANSI-type test switch and plug assembly transforms these complex tasks into a single, repeatable operation. The ODES TSBA Series Test Switch from ODES is purpose-built for this environment. It inco

Wiring and CT Short-Circuit Logic in the ODES TSB-14 Testblock
During protection testing, engineers often need to isolate the protection relay from its connected CT, PT, and control circuits while maintaining circuit integrity and operator safety. The ODES TSB-14 Testblock , when paired with its test handle, performs three critical tasks in one motion: Controlled isolation between the relay and external circuits. Automatic CT short-circuiting to protect the CT secondary. Structured timing that guarantees “short first, open later.” T
