On\u00a0November 13, 2025<\/strong>, Tengyi Electric, a premier global manufacturer of power transmission and distribution equipment, was honored to welcome a distinguished technical delegation from\u00a0Dominique<\/strong>. The primary objective of this high-level visit was to conduct a rigorous Factory Acceptance Test (FAT) and site inspection for a bespoke order of\u00a0Three-Phase ANSI\/IEEE Standard Pad-Mounted Transformers<\/strong>.<\/p>\n\n\n\n

As a manufacturer dedicated to engineering excellence, this visit underscores Tengyi Electric\u2019s growing footprint in the Caribbean energy market and our capability to meet the stringent technical requirements of island grid systems.<\/p>\n\n\n\n

Meeting ANSI Standards: A Focus on Technical Precision<\/h3>\n\n\n\n

The Dominican client requires robust infrastructure capable of withstanding tropical maritime environments. Consequently, the transformers manufactured by Tengyi for this project were engineered strictly in accordance with ANSI\/IEEE C57.12.00<\/strong> and C57.12.34<\/strong> standards.<\/p>\n\n\n\n

Upon arrival, the delegation was accompanied by Tengyi\u2019s Chief Engineer and the International Project Management team. The inspection focused on the customized “American-style” box-type transformers (Pad-mounted), specifically designed with a dead-front configuration<\/strong> to ensure maximum safety for operators and the public.<\/p>\n\n\n\n

The Factory Acceptance Test (FAT) Process<\/h3>\n\n\n\n

The core of the visit was the comprehensive FAT carried out in our High-Voltage Testing Laboratory. Under the observation of the Dominican engineers, Tengyi technicians performed a series of critical tests to verify performance parameters and reliability:<\/p>\n\n\n\n

    \n
  1. Visual and Dimensional Inspection:<\/strong> Verification of the tank construction, corrosion-resistant powder coating (essential for salt-spray resistance), and the layout of the High Voltage (HV) and Low Voltage (LV) compartments, including Bay-O-Net fusing and load break switches.<\/li>\n\n\n\n
  2. Ratio and Polarity Tests:<\/strong> Confirming the precise voltage transformation ratios across all tap changer positions.<\/li>\n\n\n\n
  3. Winding Resistance Measurement:<\/strong> Ensuring the integrity of the copper\/aluminum windings and internal connections.<\/li>\n\n\n\n
  4. Insulation Resistance & Dielectric Tests:<\/strong>\n
