What else can I help you with?
What are the effects to the transformer insulation of single phasing on a three phase Delta-Wye connection?
The effect of the insulation is to stop electric currents flowing where they should not.
What tests you carry out on transformer to prepare for first energising?
Before the first energizing of a transformer, several critical tests should be conducted to ensure its integrity and functionality. These tests typically include insulation resistance testing to assess the condition of the insulation, power factor testing to evaluate the dielectric properties, and winding resistance measurements to check for proper connections and balance. Additionally, a megger test may be performed to measure the insulation resistance against ground, and a transformer turns ratio (TTR) test is conducted to verify the correct turns ratios of the windings.
What are the conditions for operate the three phase transformer?
The BDV value of the transformer oil should be above 50kv winding resistance value should me minimum depends upon the KVA Of trans earthing should be provide for the trans air should be release inside of the tranformer insulation level should be check to operate the transformer these are all the initial condition to operate the trans
What type of insulation should be used for basement walls?
Rigid foam insulation is commonly recommended for basement walls due to its moisture resistance and high insulating properties.
What does a textile do?
The work of textile designer is to innovate a suitable weave with all desirable properties , so that the design ,after conversion to fabric should posses all properties that a a quality fabric has. He simulates the fabric prior to production and decides based on that.

What is the properties of good transformer oil?
The main function of transformer oil is insulating and cooling of the transformer. It should have the following properties:High dielectric strengthLow viscosityFreedom from inorganic acids, alkali, and corrosive sulfurResistant to emulsificationFreedom from sludging under normal operationRapid settling of arc productsLow pour pointHigh flash point
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.
What are five types of insulators?
Question should be clear For Thermal insulation,Electrical insulation,energy insulation vision insulation.
