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.
Q:What are the manifestations of insulation aging of the windings in dry-type transformers?
A:The insulation layer of the windings has changed color, cracked and fallen off; the insulation resistance and polarization index have significantly decreased; there is local overheating and peculiar smell during operation; abnormal discharge sounds occur.
Q:What are the special selection requirements for transformers that are matched？
A:It features low loss and low noise; the short-circuit impedance needs to match the inverter; it has strong resistance to voltage fluctuations and harmonic impacts; the transformer for photovoltaic power stations needs to adapt to significant changes in load throughout the day and night; the transformer for wind power needs to be able to withstand outdoor high-altitude and low-temperature environments, with a protection level of no less than IP54.
Q:What are the reasons for the three-phase voltage imbalance in the transformer?
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.
