6 Reasons Causes Of Transformer Noise

What are the causes of transformer noise?The sound power of any mechanical vibration is determined by the rate at which the noise source radiates energy. Flow rate must be described in terms of direction, so sound intensity is a vector, whereas sound pressure is a scalar, with only magnitude and no direction. Most transformer noise measurements can be done with ordinary microphones, which measure sound pressure only.

What Are Oil Intrusion Transformer’s Performance Characteristics?

Industrial and mining enterprises as well as civil buildings use oil-immersed transformers to convert network voltages of 10(6)kV or 35kV to busbar voltages of 230/400V. Suitable for AC 50/60Hz, three-phase maximum rated capacity of 2500kVA, can be used indoors, and can be installed on a pole when the capacity is 315kVA and below, and the ambient temperature is not higher than 40°C, not lower than -25°C, the relative humidity is not greater than 90% (ambient temperature is 25°C), and the altitude is not higher than 1000m.

The Best Way To Analyze And Judge A Transformer Fault

There are two ways to judge the fault of the transformer: intuitive judgment and analysis judgment. The fault analysis and judgment of transformers are mainly judged by the damage to the iron core as well as the short circuit between turns of the winding of the transformer.

What Makes Ferrite Core Transformers So Popular?

Transformers with ferrite cores are non-conductive, ferromagnetic compounds with ferrite windings. Low coercivity and low eddy current losses make them ideal for high frequency applications.
Ferrite core transformers provide consistent performance under a variety of conditions, which is why they are so widely used in the electrical industry.
