    • Proportion: 18% (2000), 17% (1999)
  • 24 Hours

    • a = number of interruptions restored within 24: 0 (2000), 0 (1999)
    • b = Total number of Class C interruptions: 107 (2000), 149 (1999)
    • Proportion: 0% (2000), 0% (1999)

(b) Target for 2000 / 2001 year

  • 11kV: 7.39

(c) Average Target for 2000 / 2001 to 2004 / 2005 years

  • 11kV: 6.36

6 The total number of faults per 100 circuit kilometres of underground prescribed voltage electric line

  • 11kV: 2.27 (2000), 0.00 (1999), 0.00 (1998), 0.00 (1997)

7 The total number of faults per 100 circuit kilometres of overhead prescribed voltage electric line

  • 11kV: 8.10 (2000), 11.43 (1999), 9.05 (1998), 12.08 (1997)
