Transformer protection with oil regeneration system

Image
  The increasing demand for electricity has taken a toll on transformers which are burdened with stress and overheating and result in breakdowns. The significance of maintaining the  transformer insulating oil  in good condition and mitigating  oil deterioration  has been widely acknowledged in the industry. Ageing of transformers have received increased focus in the recent past, owing to their relation with oil deterioration and  oil regeneration system  of  transformer insulating oil. When oil and paper, the two main players of insulation, age, they produce acids and moisture. Such by products must be identified and removed so that ageing is controlled and longevity is enhanced. Besides, measuring these byproducts reveal intensity of the ageing process. Acidity and humidity of the paper enlightens about the ageing that the cellulose insulation went through. The physical, chemical and functional attributes of  transformer insulating ...

Significance of transformer drying oven in removing moisture

  Transformer drying process removes traces of moisture in the transformer oil, besides enhancing insulation resistance and flashover voltage of transformers. The drying process is almost a part of production and is done regularly. Moisture management is an important aspect of transformer maintenance because moisture is connected to ageing and deterioration of the equipment. When the insulation gets damp and accumulates moisture, its functionality and heat transfer are affected. Insulation between various phases of the transformer is important attribute because it decides the lifespan of the transformer. Paper and insulating oils are insulation medium and insulation is affected when such paper absorbs water which in turn conducts electricity. If insulation of the transformer is not in prescribed levels, it results in surge of electricity which the transformer might not withstand and ultimately breakdown or collapse in failure. The transformer drying oven distinguishes pressu...

Interferential therapy

  One of the non invasive pain management therapy employs electrical stimulation to heal and relieve pain in damaged tissues. Interferential therapy , as it is known, also boosts the body’s ability to respond to pain, besides accelerating blood circulation and produces hormones to enhance healing process. A constant frequency is applied to one of the electrodes in a pair to which a slightly different frequency is applied to another electrode. Together, they produce an amplitude modulated medium frequency also known as beat frequency, in the tissue. Four pole configurations are also used for healing purposes in i nterferential therapy . These intermittent pulses block pain signals and stimulate affected tissue and relieve pain. IFT is basically used for treating chronic, post traumatic, post surgical pains. Spine specialist Dr Karunakaran, backed by more than two decades of experience, provides inferential therapy in Chennai.   https://in.pinterest.com/pin/88...
