How do you calculate knee point voltage?
Step 1: calculating knee point voltage Vkp Vkp = {2 x Ift (Rct+Rw)}/ k Vkp = required CT knee point voltage Ift = max transformer through fault in ampere Rct = CT secondary winding resistance in ohms Rw = loop impedance of pilot wire between CT and the K = CT transformation ratio Step 2: calculate Transformer through fault Ift Ift = (KVA x 1000)/(1.732 x V x Impedance) KVA = transformer rating in kVA V = transformer secondary voltage Impedance = transformer impedance Step 3: How to obtain Rct To measure when CT is produce Step 4: How to obtain Rw This is the resistance of the pilot wire used to connect the 5th class X CT at the transformer star point to the relay in the LV switchboard. Please obtain this data from the Electrical contractor or consultant. We provide a table to serve as a general guide on cable resistance. Example: Transformer Capacity : 2500kVA Transformer impedance : 6% Voltage system : 22kV / 415V 3phase 4 wire Current transformer ratio : 4000/5A Current transformer type : Class X PR10 Current transformer Vkp : 185V Current transformer Rct : 1.02½ (measured) Pilot wire resistance Rw : 25 meters using 6.0mm sq cable = 2 x 25 x 0.0032 = 0.16½ Ift = (kVA x 1000) / (1.732 x V x impedance) = (2500 x 1000) / (1.732 x 415 x 0.06) = 57,968 round up 58,000A Vkp = {2 x Ift (Rct+Rw) } / k = {2 x 58000 (1.02+0.16) } / 800 = 171.1½
What is the percentage of 3.5 from 58000?
3.5 ÷ 100 × 58000 = 2030 So 3.5% of 58000 is 2030Therefore, 3.5% from 58000 is: 58000 - 2030 = 57970
What is 3 percent of 58000?
3% of 58000 = 3% x 58000 = 0.03 x 58000 = 1740
How much is 25 percent off 58000?
10 % of 58000 is 5800 5 % of 58000 is half of 5800 is 2900 25 % of 58000 is two times 5800 plus 2900 is 11600 plus 2900 is 14500 25 % off 58000 is 58000 - 14500 = 43500

What is 57999 times 2?
57999 * 2 = 115998 The easiest way to do this is to note that 57999 = 58000 - 1 So, 57999 * 2 = (58000 -1)*2 = 58000*2 - 1*2 = 116000 - 2 = 115998
