CONDUCTANCE & CONDUCTIVITY

CONDUCTANCE

  • It is the measure of how easily the current will flow through the conductor.
  • The reciprocal of Resistance is called CONDUCTANCE and is denoted by "G".
  • Its unit is "MHO" or "SIEMENS".         
  • G = 1/R = I/V.

CONDUCTIVITY

  • Conductivity or SPECIFIC CONDUCTANCE is the reciprocal of specific resistance.
  • It represented as σ (SIGMA) and its unit is Mho/Mtr.
  • σ = 1/ ρ.

TRANSFORMER RATING CALCULATION

Image
 TRANSFORMER RATING CALCULATION In this BLOG, we are going t discuss about the Calculation of   TRANSFORMER RATING : For Eg:- Maximum Load = 400KW. Diversity Factor = 0.7 Therefore, Expected Load in KW = 400*0.7 = 280KW Expected Load in KVA = 280/ 0.9 = 311KVA (Power Factor Considered as 0.9) 85% Loading Capacity is considered. Required KVA Rating = 311/ 0.85 = 366KVA Therefore, 400KVA transformer is used.  (400KVA is the n ext Available Rating above 366KVA) For More Topics: Follow Us On: FACEBOOK

LAW'S OF RESISTANCE

Image
LAW'S OF RESISTANCE The RESISTANCE of a Conductor varies, Directly with its LENGTH . Inversely to its CROSS-SECTIONAL AREA. Depends on NATURE of the materials. Depends on the TEMPERATURE.                                       R  ∝  L,  R  ∝  1/ A                                       R   ∝  L/A                                       R  =  ρ  * (L/A) Where   ρ is called SPECIFIC RESISTANCE (RESISTIVITY) and its unit is Ohm-Mtr .
