Product catalog summary
Introduction
Trench is a leading manufacturer of high voltage equipment, specializing in Instrument Transformers for 69-800 kV systems. These transformers convert high transmission voltages to standardized low values for metering, protection, and control. This document focuses on the VEOT and VEOS types of inductive voltage transformers.

Features
The VEOT and VEOS transformers feature a refined oil/paper insulation system, low weight, and minimal oil volume. They use high-quality, PCB-free mineral oil and offer excellent seismic performance. The design includes hermetically sealed stainless steel bellows for units rated 123 kV and above, and they are explosion-resistant with a high-reliability insulating system.

Specifications
These transformers meet IEC and ANSI metering and protection classes, with standard thermal burden ratings of 2000 - 2500 VA. They are maintenance-free for over 30 years and have stable accuracy over time. The VEOT is suitable for up to 300 kV, while the VEOS is for applications above 300 kV.

Construction
Key construction features include aluminum flat pad primary terminals, stainless steel expansion bellows, and a secondary terminal box. Optional equipment includes a gas detection system and composite insulators.

Electrical and Mechanical Data
The document provides detailed electrical and mechanical specifications, including maximum continuous operating voltage, impulse withstand voltage, and creepage distances for various VEOT and VEOS models.

Contact Information
The document lists contact details for Trench facilities worldwide, including locations in Austria, Brazil, China, Canada, France, Germany, Switzerland, and the UK.

Conclusion
Trench's VEOT and VEOS inductive voltage transformers are designed for reliability and performance in high voltage applications, with a proven track record since 1926.
