{Note: Energy data held in a network operator’s metering installation must be
secured in accordance with clauses 4.8(4)(a) and 4.8(5).}
3.9 Metering installation types and accuracy requirements
(1)
Subject to clause 3.9(2), the “Type” for a connection point (and for a metering installation for the connection point) is shown in the first column in Table 3 in Appendix 1, on the row in which the connection point’s annual load is shown in the second column.
(2) A connection point is Type 7 if it is associated with one or more of the following
loads:
(a) street, traffic, park, community, or security lighting; or (b) ticket issuing machines, parking meters, or community watering systems; or (c) telephone service requirements; or {Example: Telephone service requirements may include telephone boxes, fibre optic cable routers and devices that connect pay television services.}
(d) loads consuming less than the starting electric current of a meter; or (e) other loads of a similar nature.
7 December 2012 GOVERNMENT GAZETTE, WA 6065
(3) Subject to clauses 3.9(4), 3.9(5) and 3.9(7), each metering installation must meet at least the requirements for that Type of metering installation specified in Table 3 in Appendix 1. {Note: Without limiting clause 3.9(3), a network operator must ensure that the incidence and magnitude of burden changes on any secondary winding supplying its metering installation do not cause the accuracy of the metering installation to fail to meet the requirements of Table 3 in Appendix 1 for that Type of metering installation.}
(3A)
If the user and the network operator cannot agree on the Type of metering installation to be installed at a connection point, then subject to clause 5.1 the network operator may make a determination on the matter.
(3B)
A network operator’s determination under clause 3.9(3A) may be the subject of a dispute under this Code, or if applicable an access dispute under the Access Code, a dispute under the market rules, a dispute or a complaint under the Code of Conduct or a dispute under the Customer Transfer Code.
(4)
A network operator (acting in accordance with good electricity industry practice) may determine that the maximum allowable clock error for a Type 4 or Type 5 metering installation is to be greater than that specified in Table 3 in Appendix 1 in order to accommodate evolving whole-electric current technologies, provided that such relaxation is consistent with the Code objectives.
{Note: Under clause 1.5 this ability to relax the clock error will be
subject to the National Measurement Act and other enactments.}
(5)
A network operator (acting in accordance with good electricity industry practice) may determine that the maximum allowable clock error for a Type 6 metering installation is greater than that specified in Table 3 (read with Table 4 to Table 7 in Appendix 1) providing that such relaxation is consistent with the Code objectives.
{Note: Under clause 1.5 this ability to relax the clock error will be
subject to the National Measurement Act and other enactments.}
(6) Subject to clause 3.1, it is acceptable to use direct connected meters for Type
4 to Type 6 metering installations.(7)
For a metering installation used to supply a customer with requirements above 1000 volts that require a VT and whose annual consumption is below 750 MWh, the metering installation must meet the relevant accuracy requirements of a Type 3 metering installation for active energy only.
{Note: The 1000 volt limit derives from AS 3000-2000.}
(8) For the purposes of this clause 3.9, the method for calculating the overall error of a metering installation is the vector sum of the errors of each component part, i.e. a + b + c, where: a = the error of the VT and wiring b = the error of the CT and wiring c = the error of the meter.
(9) If compensation is carried out within the meter then the resultant metering
system error must be as close as practicable to zero.
6066 GOVERNMENT GAZETTE, WA 7 December 2012

{Note: Substitution methods 11 to 18 apply to Type 1 metering installations to Type 4 metering installations. Substitution methods 51 to 56 apply to Type 5 metering installations.}
(1) This clause A3.3 applies in respect of Type 1 metering installations to Type 5 metering
installations.(2) Substitution Method 11
(a)
Interval energy data obtained from another meter at the same measurement point for the same interval data periods as that being substituted for may be used for substitution purposes, e.g. installations where revenue and check meters are installed.
6146 GOVERNMENT GAZETTE, WA 7 December 2012
(b)
Method 11 substitutions also include the use of data from similar meters where the load profile of the second meter is a good match to the load profile of the meter for which substitutions are being made, e.g. where meters are installed on each end of a transmission line where the difference due to line losses can be accurately determined; where meters are installed on parallel feeders where supply is ‘to’ and ‘from’ common buses and line impedances are similar.
(3) Substitution Method 12 Data values may be calculated for an unknown feed to a node based on the other known energy flows to or from that node.
(4) Substitution Method 13
(a)
Data from an energy management system or SCADA data may be used for substitution purposes, where the data originates from a similar measurement point as the meter for which substitutions are being made.
(b)
Data from an energy management system or SCADA data may be data which is inferior in accuracy or resolution and which is in a dissimilar format to the energy data, (e.g. 30 Min. demand values). It may be necessary to adjust the data in both magnitude and form in order that the substitution is of an acceptable quality.
(5) Substitution Method 14
Where data substitution methods 11, 12, and 13 cannot be carried out, then the network operator200 may substitute for the missing data using the “Nearest Equivalent Day” or “Like Day” method, as detailed in the table below.

[201] If clause 5.29(b) applies, read “network operator” as “metering data agent”.METHOD 15
The intervals to be substituted will be plugged using an average of each interval from the proceeding 4 weeks, or part thereof.
This averaging technique may be applied in the following ways:
a) where the averaged intervals are simply ‘plugged’ into the intervals requiring substitution.
b) where the averaged intervals are used to provide the profile for the ones to be ‘plugged’ to a pre-determined numberof pulses for the total substitution period.
However if data is required to be substituted for a public holiday then the most recent available Sunday will be used.
(7) Substitution Method 16
(a) Where data substitution is required for any period greater than 7 days, consideration, consultation and agreement must take place between the affected parties to resolve any abnormal equivalent days that may be applicable. (b) Method 16 substitutions are: (i) data substitutions of any format for periods greater than 7 days that are based on an agreement between all the affected parties;
(ii) changes to existing substitutions for any period that are carried out where the affected parties have directed that as a result of site or customer specific information, the original substitutions are in error.
(8) Substitution Method 17 Data substitutions for periods up to, but not exceeding 2 hours, may be carried out by simple linear interpolation.
(9) Substitution Method 18 This substitution method covers the situation where an alternate method of substitution has been agreed with the market participant, the applicable user and the network operator[202]. This may be a globally applied method or a site specific method where an
adjusted profile is used to take into account local conditions which affect consumption (e.g. local holiday or customer shutdown), or where alternate data may be able to be used for quality checks and minor adjustments of an estimated profile such as using meter register data.
