In June 2026, Daelim Transformer supplied a custom batch of 72 units of 1000 kVA VPE-type dry-type transformers to an integrated energy service provider in Florida, USA, specializing in microgrid and distributed energy solutions. These transformers are primarily deployed in local microgrids to provide galvanic isolation. They help block DC components and high-order harmonics generated by photovoltaic inverters or battery energy storage systems (BESS), reducing their propagation through the electrical system. In addition, the Dd0 vector group helps prevent circulating currents and provides electrical isolation between the primary and secondary sides, helping to manage ground potential differences and maintain power quality and operational safety for microgrid busbars and distributed energy systems.

Key Features

NEMA 3R Enclosure with Space Heaters

This Daelim Transformer 1000 kVA dry-type transformer features a NEMA 3R stainless steel enclosure suitable for outdoor installation and designed to protect against rain, snow, and ice. It is equipped with internal anti-condensation heaters that operate in conjunction with a thermostat or humidistat. These heaters warm the air inside the enclosure in low-temperature or high-humidity conditions, helping to prevent condensation during periods of significant diurnal temperature fluctuations. This helps protect internal electrical components, terminals, and control equipment from moisture and condensation, supporting reliable operation.
