IS 2584-1963

  1. 1. Method of Test for Electric Strength of Solid Insulating materials at Power Frequencies IS:2584-1963 Presentation by: Dhritika Saikia MT/11/PSE/07
  2. 2. Glimpse  Adopted in 14th August 1963  Reaffirmed in 2001
  3. 3. This standard lays down test condition and procedure for the determination of electric strength of solid insulating materials and filling compounds for industrial purposes at power frequencies
  4. 4. Effects on electric strength  Frequency, waveform and time of voltage application  Thickness and homogeneity  Presence of mechanical strength  Presence of gaseous inclusions, moisture or other contamination  Size, shape and thermal characteristics of test electrode.  Electrical and thermal characteristics of the ambient medium
  5. 5. Conditions to be evaluated
  6. 6. General Conditions  Surrounding medium Liquid Conditioning of Test specimen Conditions of test In Air In Liquid
  7. 7. Electrical equipments  High voltage transformer  Voltage Controlgear  Protective gear  Measuring instruments
  8. 8. Test specimens and electrodes • Surface in contact with electrodes are parallel, Test smooth, flat specimen • The area should be able to prevent flashover • Free from pitting • Leads should not affect the Electrodes electric field configuration • Should not affect the pressure of the specimen
  9. 9. Board and sheets
  10. 10. Board and sheets
  11. 11. For test parallel to the surface and along the laminae Board and Tubes and sheets cylinders
  12. 12. Electrode arrangement for testing boards and sheets parallel to the surface and along the laminae
  13. 13. Application of voltage
  14. 14. Conclusion
