Page 14: Introduction
During its operation, the SDV aims to maintain the quality of the voltage in the load, that is, within a given range of values, programmed by the user. For this, in addition to performing the ANSI 90 function, the SDV presents a series of applications to meet the most demanding regulations of the electricity sector.

Page 23: Figure 2 - Graph Representing The Oltc Checking Limit
OLCK - Verification of successful tap changing Enabled, this function allows the SDV to verify the tap changing success by means of voltage changes after the regulation command (increase/decrease voltage), without the need to measure the tap position. The algorithm applied to this verification method performs the comparison between the initial voltage levels and the one presented after the command for tap changing.
Page 24: Basic Operating Philosophy
CTs (required accessory, supplied separately). 2.5.1.2 Forced cooling control The SDV can command up to 2 groups of forced cooling, in manual or automatic mode. In automatic mode, the forced cooling groups are controlled based on the highest measured value among the temperatures of windings 1, 2 and 3 or based on the oil temperature, depending on the parameterization.
Page 25 2.5.1.3 Multigradient function The SDV has a multigradient function, as the thermal behavior of a transformer varies according to the activation of its cooling stages. This functionality allows the equipment to vary the thermal parameters according to the active cooling stage. The winding temperature is calculated with greater precision, according to the operation of the transformer, ensuring greater reliability in the thermal management of the asset.

Page 46: Temperature Sensors
Figure 18 - Central tap indication TEMPERATURE SENSORS The SDV has two inputs for RTD Pt100 Ω at 0 °C type temperature sensors. One of them must be used to measure the temperature of the top of the transformer oil; the other can be used to measure ambient temperature, transformer oil temperature redundancy, tap changer oil temperature, or to another desired temperature.
Page 47: Figure 19 - Connecting The Shield In The Interconnection Between Rtd Sensors And The Sdv
The temperature sensor must be connected to the SDV through shielded cables, without interrupting the mesh, which must be grounded only at the end connected to the SDV, as close as possible to it. If there is a need for intermediate terminals for interconnecting the RTD sensor, the cable shield must pass through the terminal, preventing its interruption.
Page 48: Figure 20 - Connection For Single-Phase Transformer, 0° Phase Difference
CT of the equipment is short-circuited and grounded in the panel terminals. If the SDV has the regulation functionality, the input where the external CT for regulation is located must be informed in the configuration. This external CT is a window type with a non- sectionable core, unlike the clip-on CT that is normally used for thermal imaging.
