Changes of voltage at customer’s consumers terminals

In force

(1)

Supply of electricity by an electricity entity to a customer must be maintained at the standard voltage for the supply mentioned in section 11 or 12.

(2)

For the supply of electricity at low voltage before 27 October 2018, the supply is taken to be maintained at the standard voltage for the supply if the voltage at a customer’s consumers terminals—

(a)

for the standard voltage mentioned in section 11(2)(a)(i) or (b)(i) or (3)(a)(i) or (b)(i)—does not differ from the standard voltage by more than the percentage stated for the supply voltage range in AS 60038; or

(b)

for the standard voltage mentioned in section 11(2)(a)(ii) or (b)(ii) or (3)(a)(ii) or (b)(ii)—is no more than 6% more or less than the standard voltage.

(3)

For the supply of electricity at low voltage on or after 27 October 2018, the supply is taken to be maintained at the standard voltage for the supply if the voltage at a customer’s consumers terminals—

(a)

for supply before 1 July 2020—does not differ from the standard voltage by more than the percentage stated for the supply voltage range in AS 60038; or

(b)

otherwise—

(i)

is within the minimum preferred steady state median voltage and the maximum preferred steady state median voltage stated in AS 61000; or

(ii)

if the voltage can not be maintained under subparagraph (i)—does not differ from the standard voltage by more than the percentage stated for the supply voltage range in AS 60038.

(4)

The supply of electricity at high voltage is taken to be maintained at the standard voltage for the supply if the voltage at a customer’s consumers terminals is—

(a)

for the supply of electricity at a voltage of 22,000V or less—no more than 5% more or less than the standard voltage; or

(b)

for the supply of electricity at a voltage more than 22,000V—within the margin agreed between the electricity entity and the customer.

(5)

For measuring the voltage at a customer’s consumers terminals for subsection (2), (3) or (4), the methodology for the measurement of steady state voltage stated in AS 61000 must be used.

(6)

In this section—

AS 61000 means AS 61000.3.100 (Limits—Steady state voltage limits in public electricity systems) as in force from time to time.
