Summary of Design

This document serves as the general Technical Desription for the Medium Voltage step-up Transformers (henceforth MVT) integrated in SMA’s Medium Voltage Power Platforms.

The MVTs described herein are of a padmount design, using a four-winding, double story construction, providing galvanic isolation between the inverter ourput circuits, as shown below. They are constructed with two individual low voltage windings, and two medium voltage windings, with the medium voltage windings paralled to the output bushings.

For reference only, Dy1y1 vector group shown with 5 position tap changer SMA has established a configurable product, harmonized to the Medium Voltage Power Platform product portfolio. The MVTs are designed for a minimum service life of 25 years, and are suitable for outdoor applications.

Accessories

3.2.1 Gages and Alarm Contacts

The transformers include as standard accessories, gages with form C, dry alarm contacts, for Overtemperature (8). The Overtemperature alarm contacts are preset for 105°C (Alarm) and 115°C (Trip).

As an available option, additional gages and alarm contacts can be provided for Over-pressure (7,9,10), and Liquid Level (8). The gages are located in a NEMA 1 enclosure mounted to the left hand side of the transformer tank. The enclosure is able to be locked with a customer-supplied LOTO hasp and lock. The contacts are rated for 230 VAC.

The terminal blocks for the alarm contacts are located in a separate, NEMA 3R control box (14) on the left hand side of the transformer tank.

3.2.2 LV Fuse Block

The transformer, if ordered with option 3_1: 80A Internal MVPP Control Power, will include a 100 A fuse block with 80A, Class J fuses (16).

This fuse block is tapped from one set of low voltage bushings, and provides the overcurrent protection for the supply conductors to the low voltage power distribution of the Medium Voltage Power Platform.

3.2.3 Sampler Valve

A sampling valve for the dielectric fluid is included in a separate external enclosure on the lower left hand side of the High Voltage side of the transformer tank (13).

3.2.4 Medium Voltage Switch

The transformer includes a three phase, under oil, two position load break switch (4).

The switch is located in the same NEMA 1 external cabinet as the gages, on the left hand side of the High Voltage side of the transformer tank.

3.2.5 Grounding

A grounding bus bar of tin plated copper is included in the low voltage compartment of the transformer (15). It is mounted to the lower left hand side of the sidewall of the low voltage compartment.

This grounding bus receives the equipment grounds of the components on the Medium Voltage Power Platform (MVPP), and has terminations for the conductors which connect to the exterior ground pads of the MVPP, as detailed in the MVPP circuit diagrams.

General Design • • • •

16

The MVTs are suitable for operation with pulsed inverters. The MVTs are designed for voltages on the low voltage windings, that can exhibit a voltage gradient dU/dt of up to 500 V/µs to ground. A shield winding is included between the low voltage and high voltage windings, grounded to the tank, which serves as an additional dU/dt filter. The MVTs are designed to tolerate the voltages that arise during pulsed operation of the inverters. These voltages can exceed the RMS voltages, and are considered in the design of the insulation.
