Presentation Transcript

  1. Rectifier and Bond Reading Tim Jenkins

  2. Basic Electric - Shunts

  3. Basic Electric - Shunt Formulas • Calculate Current • Given - Shunt ( .01 ohms & voltage across the shunt = 50 Mv) • Convert units of voltage, 50mv = .05v • Calculate current using Ohm’s law • I = .05 v/.01 ohms = 5 amps • Given - Shunt ( 15 amps, 50mV) • Measured voltage drop = 28mV • Determine shunt rating • Rating = 15 amps/50mV = .3 amps / mV • Calculate current • Current = .3 amps / mV x 28 mV = 8.4 amps

  4. Slide Resister Application

  5. Resister Wire Application The amount of Resistance is made by the Length of the Wire.

  6. Disconnect Bond Wire for Amp Drain Reading

  7. 1.36 Amp Current Drain Make Connection in series with the Circuit Amp Drain Reading

  8. Slide Resister Lighting Arrestor

  9. Connection Made on Resister from Foreign Structure and Columbia.

  10. Disconnection to get Amp Drain must be made in series with the circuit.

  11. Direct Bond Connection, No Resistance

  12. Shunt Resister

  13. Measuring Amp Drain by Measuring Voltage Drop Across the Shunt. Ratio is normally found on Shunt. .001V = 1A

  14. 7 milivolts = 7 Amps Make connection across Shunt. Polarity does not matter.

  15. Ratio for Shunt Shunts do not have to be disconnected in BI-monthly and Annual inspection.

  16. Alternative method – use shunt for amp readings. Take mili-volt reading across shunt then use ratio to figure total amps. Connect meter in serious for amp reading on the structure or anode wire.
