Klippon® Connect TTB instrument transformer Product innovation

Klippon® Connect TTB instrument transformer Product innovation

In T&D applications, current and voltage transformers are mainly used for protection and measurement functions. Our new TTB range of Klippon® Connect instrument transformer terminal blocks have been designed to meet all the connection requirements of these two critical applications. The wiring of current and voltage transformers can be carried out particularly easily and safely with the new terminal block series – even within complex circuits. The prevention of operating errors during operation increases plant availability and extends the life cycle of the entire control cabinet. Thus, the respective requirements of the end-user are fulfilled to the highest degree.

Protection
Protection relays have an extremely important and critical function in T&D grids as they have to detect and isolate faults in the shortest possible time. Their connection with Current and Voltage transformers not only has to be SECURE but also SIMPLE and SAFE. The simplicity is very important in the design/standardisation of the required protection circuits (engineering stage) and the safety is crucial to avoid that potential human mistakes during maintenance operations can affect either personnel or devices.

Metering
Indirect and Semi-Direct Metering applications also require SECURENESS, SIMPLICITY and SAFETY in the connections with Current and Voltage transformers. However, there are some peculiarities in this application that require a certain FLEXIBILITY that could affect the SAFETY (eg. connection of a pattern serial ammeter from time to time). Our Klippon® Connect TTB range terminal blocks also cover the specific requirements of Metering connections providing the right solutions to perform all the necessary tests without affecting the safety of personnel and devices.
