The manual provides exhaustive pin-out diagrams. Since SIPROTEC 5 devices are modular, the 7UT82 can be customized with various I/O modules. The manual details the default terminal assignments for current transformer (CT) inputs and binary signals. 2. Functional Description: Differential Protection (87T)
The manual for the 7UT82 is a critical document for protection engineers, commissioning technicians, and maintenance personnel. It serves as the definitive guide for the hardware installation, software configuration, and electrical theory behind the relay’s operation.
Expandable binary inputs and outputs with highly sensitive thresholds for tripping and signaling.

Provides highly sensitive coverage for ground faults near the transformer neutral point. The 7UT82 supports both high-impedance and low-impedance REF methods, explicitly documented with wiring schematics within the device manual. 49 - Thermal Overload Protection Uses a mathematical thermal replica model based on I2tcap I squared t The manual provides exhaustive pin-out diagrams
The manual details how to use to configure the relay, map analog inputs, and set differential protection parameters. It provides guidance on using the CFC (Continuous Function Chart) for creating custom logic. 2. Functional Scope
