Frequently Asked Questions (FAQ)

Q:What are the reasons for excessive noise when the transformer is operating? How can the noise be reduced?

A:Reasons: Loosening of core, deformation of windings, resonance of components, failure of cooling system, influence of grid harmonics. Measures: Tighten the core clamps; Correct the position of windings; Adjust the shock absorption devices of cooling fans / oil pumps; Install soundproof covers; Address grid harmonics.
A:The positions of the transfer switch are inconsistent; there is a short circuit between the windings (in a certain phase); the three-phase load is severely unbalanced; the system voltage is unbalanced across the three phases.
A:Minor leakage: Tighten the flange bolts of the casing and replace the sealing gasket; Severe leakage: Replace the casing after power outage; If the insulation inside the casing gets damp, conduct an insulation test and replace the casing if necessary.
A:We provide comprehensive end-to-end solutions and services, covering the entire process from electrical and mechanical design, quality control, material selection, core processing, winding, assembly, insulation, and testing to packaging.
