ISOLATION TRANSFORMER IN DATA CENTER

-

ISOLATION TRANSFORMER :
  1.  Outputs will be isolated from inputs.
  2. Since the output connection is totally isolated from input connection any fault like short circuit in primary winding are not reflected on secondary side .
  3. Any faults, harmonics or Electrical disturbances or surges in primary side of transformer  are not transferred to secondary side due to Galvonic isolation on primary side .
  4.  Interference can be restrained with it.
  5.  The neutral-ground voltage will be reduced.
  6.  Faults can be isolated.
  7.  Low-frequency 3n-order harmonics will  be restrained .
  8. Isolation transformers  are the only way of eliminating general mode noise.
  9.  They also provide better safety to any equipment by Galvanic isolation.
  10.  They separate the device from the main power supply upon any electric shocks. So, they ensure that the concerned electric and electronic appliances are safe and secured for a longer time.
  11.  Isolation transformers are used to provide better quality power to the telecommunication equipment. Surges, spikes, and other such power-related problems may cause an irritating sound which interferes with the normal functioning of such devices. Isolation transformers prevent such problems. They improve the power quality and ensure that the telecommunication equipment is efficient and safe.
  12.  Provides Electromagnetic and Electrostatic shielding .
  13. Provides perfectly balanced neutral at zero potential.
  14. Reduces Noises, Spikes, Surges, Transients, stress on semiconductor components.

  • Note : Generally Isolation transformer has Major Application  in Datacenter to protect sophisticated Electronic devices , Servers , mainframes from all electrical faults and disturbances .
  • Isolation transformer voltage ratio is 1:1 , but there are special Isolation & Ultra isolation transformers which can step down and step up voltage based on applications. 
ISOLATION TRANSFORMER

 
ISOLATION TRANSFORMER


  • K-13 Rated Isolation Transformer Reduces 3rd, 5th, 7th, 9th & 11th Harmonics order .
  • K-13 Rated Isolation Transformer had Delta -ZigZag Star Connection which provides 30 degree Phase shift for 3rd and higher order Harmonics .


ULTRA ISOLATION TRANSFORMER



  • Ultra isolation Transformer attenuates common mode noise and transverse mode noise and provides for noise or interference free power. In principle, UIT only transfers 50 Hz.
  •  Ultra isolation Transformer  prevents transfer of RF and HF disturbances with extensive insulation between primary and secondary.
  • Ultra-K-13  transformer Attenuates triplen harmonic currents from the line. 

  • They consist of a Delta primary and a Zig-Zag secondary. The Zig-Zag secondary causes a phase shift in the triplen harmonics, which results in a canceling effect.  This prevents the triplen harmonic losses from being coupled back into the primary and results in cooler operation and increased energy efficiency

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 caus...

Transformer Magnetic Oil Gauge Indicator

conservator tank oil level (Mog) The MOG  (Magnetic Oil Gauge)  is a device by which we can supervise the level of oil inside the tank or conservator of power transformer and also gives us an alert low oil level indication .  A decrease in level of Transformer oil in Conservator is an indication of leak and therefore MOG level is an important parameter to be monitored. Practically under running condition oil level remains at 3/4 th level.

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...
