Transformer Breather

 Silica gel breather cup of a Transformer

 The silica gel breather cup of a Transformer is partially filled with oil to avoid entering of moisture into the Transformer. As the oil expands due to rise in temperature, the pressure builds up , consequently, the vapour and dry air accumulated in the conservator are breathed out.

 During the fall of temperature, oil in the Transformer contracts and creates partial vacuum in the tank which makes the Transformer to breathe in air from the outside. In the process of breathing in outside air, moisture and dust particles in the outside air are also sucked in. But, the oil in the breather cup obstructs dust particles and settles them at its bottom. The moisture entered is absorbed by the silica gel in the breather.


The oil in the breather cup is only partially filled up to the mark given on the cup. If oil in the cup is over filled, while breathing in, the oil gets into contact and absorbed by the silica gel resulting in bottom portion of silica gel is permanently wasted as the oil absorbed silica gel cannot be reactivated again.

    There is a great deal of information available about the necessity of the essential fatty acid omega 3. the various food sources that it can be obtained from well known, but concern arises for those that have restrictive menu choices due to personal or medical considerations. With all the concern over toxins found in fish the biggest question is, which is better when it comes to fish oil vs. flaxseed oil? dielectric strength

ACB Tripping settings

ACB tripping settings   Acb has 6 adjustable tripping settings 1 Long time delay (Tr ) 2 Short time delay( Tsd ) 3 Earth fault delay (Tg) 4 Long time (Ir) 5 Short time (Isd) 6 Earth Fault (Ig) Long time is for maximum overload capacity . Short time is for short circuit current Earth fault is for earth fault current . As per thumb Rule : 1. Long time set at 0.8 means 80% of full load current .Until this level of current  breaker carry without tripping  . Above 0.8 Acb trips. Long time delay causes the breaker to wait for certain time to allow heavy temporary inrush currents to pass away. Generally long time delay is set at  4 Sec. 2. Short time set at 0.6 means  60% of full load current . It determines the Amount of Current the Breaker will carry for short time period.  Generally short time delay set at 0.2 sec. 3. Earth Fault set at 0.3 or 30% of  fault current . It controls the amount of Ground Fault current that will cause the breaker to interrupt the cir

HIGHER EFFICIENCY MOTORS (HEM)

Super premium Efficiency (IE4) motors  IE4 MOTOR The higher price of the IE4 motors is due to :  1. the use of high-quality materials and optimization of assembly and design of these motors to achieve higher efficiencies upto 97% . 2.  Large-diameter copper wires and more quantity of aluminum are used in rotors of these motors to reduce the resistance losses.  3. An optimized cooling fan is also used to reduce the winding losses. 4. use of advanced technologies like diecast copper rotors enables achieving higher efficiencies in the same frame size. The use of the high-quality, expensive materials increases the overall cost of this type of motors. adoption of energy efficient technologies to reduce their energy consumption and carbon emission. 5. Stator and Rotor I2R losses: Stator and Rotor I²R losses appear when heat is generated by resistance from current flowing in the stator windings, rotor conductor bars. These are major losses, typically account for 55% to 60% of tota
