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
