PPM for Transformer:

  1. Informing department and getting Approval .
  2. Ensuring incoming & outgoing breakers in off position.
  3. Applying LOTO Tags .
  4. Using proper PPE while carrying out PPM.
  5. Cleaning T/F with dry cloth .
  6. check & Reticify Oil leakages.
  7.  check silica gel condition.
  8. check OTI & WTI control wiring & tightness .
  9. check OLTC Belt condition .
  10. Checking Manual operation of oltc .
  11. checking buccholz's relay alarm & trip test.
  12. checking for damaged nuts & bolts.
  13. check Neutral to Earth Resistance .
  14. HT To LT Megger values need to check .

ACB Tripping settings

Image
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 IĀ²R 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...
