Capacitor Voltage Transformers & Coupling Capacitors INTELLIGENT EVOLUTION Trench is the recognized world leader in the design and manufacture of Capacitor Voltage Transformers (CVT's) and Coupling Capacitors (CC's). Trench has been manufacturing CVT's since the early 1970's and installations in virtually every country in the world attest to their acceptance and reliability. In order to maintain and enhance technical excellence while retaining commercial competitiveness, product refinements Over the past several years, Trench has listened to their customers for critical inputs relating to installation techniques, testing issues, and long term reliability enhancements. A key element in product research must always include the ability to produce a product that is demonstrated to be more reliable, while keeping cost increases With this in mind, Trench has made several CVT design enhancements that will provide all customers with even higher reliability, coupled with reduced installation times. In addition, component and assembly costs are brought into closer direct control of Trench. This brochure will outline the design modifications and resultant advantages for our CVT and CC customers. Traditionally Trench CVT's used a nomenclature system that identified the model type and the nominal system voltage, i.e. TEVF 138. In order to differentiate the enhanced design CVT's, the nomenclature will now identify the same model type and the maximum system voltage, i.e. TEVF 145 orTCVT 145.

It should be noted that the enhanced design CVT's will be electrically identical to previous CVT's and all main materials used will be the same (same dielectric materials and configuration; no changes in dielectric fluids, paper and polypropylene film). The new CVT's will mount into the same locations as they will use identical mounting hole arrangements. Note that there are minor variances in height and weight when comparing the two models. Trench efforts were focused on reducing the number of components by integrating multiple individual components into single engineered items, thus reducing...
