Traceable Electrical Energy Metering Workshop
POSTPONED - Now 17th and 18th March 2020. This course is focused on understanding the steps required to make traceable measurements, will include training in the calculation of measurement uncertainties and consider the metrology implications of the changes to Part 10 of the Electricity Industry Participation Code.
This course has been delayed to allow for the changes to Part 10 of the Electricity Industry Participation Code to come into force. This will maximise the value of this course for participants and allow for better understanding of the metrology implications of the changes to Part 10.
This course is focused on understanding the steps required to make traceable measurements, and will include training in the calculation of measurement uncertainties. Students will enhance their competence in ensuring that metering components and installations are meeting the metrology requirements of Part 10 of the Electricity Industry Participation Code.
At the competition of the course students can expect to be able to carry out the Calibration and Measurement Capability (CMC) calculations required for the Class A test houses and also to calculate the uncertainty of energy metering measurements both in the laboratory and in the field.
This year emphasis will be placed on the calibration of current transformers and the effect of burden on the measured errors. Practical examples will be worked through so that each participant can return to their laboratory more confident of their work.
2 Day course - Tuesday 17th and Wednesday 18th March 2020

Principal Research Scientist | Electricity
Laurie has spent 40 years working as a metrologist specialising in electrical measurements. He is responsible for the 10 V Josephson Voltage Standard, which is New Zealand’s standard of dc voltage. In 1997 he spent 10 months working with the team at the NIST, Boulder, Colorado laboratories who developed the Josephson array chip that is the heart of this standard. He has carried out research into developments of this technology that allow the synthesis of arbitrary low-frequency waveforms. Laurie has been active in many areas of electrical metrology, including DC voltage, current and resistance.
In 1999 Laurie developed the Reference Step Method for measuring dc voltage ratios for resistive dividers up to 1000 V and has since then applied it to calibrating both dc voltage sources and meters over the same range. Several NMIs are using this method for dc voltage scaling. In 2006 he applied the core principle of this method to create the Current Reference Step Method, which can be used to scale from a low current to a much higher current (hundreds of amperes). Laurie has been a technical expert for many IANZ accredited electrical calibration laboratories and has peer-reviewed several NMIs in the Asia-Pacific region.
Distinguished Scientist | Electricity
Keith’s early scientific work was with developing primary standards of impedance, starting with a mechanical-based capacitance standard. The discovery of the quantum Hall effect in 1980 (by Klaus von Klitzing) led to a period of intense international research, and Keith contributed to the international effort that ultimately led to the adoption of the quantum Hall effect as the new standard of resistance.
He has significant experience with developing national quality infrastructures from his time spent as Director of MSL and as Chairperson of the Asia-Pacific Metrology Programme. He has provided strategic advice in Malaysia, Chile, the Philippines and Myanmar. Keith has worked closely with the New Zealand electricity supply since 1993 to support the development of metrology codes of practice for metering installations. A significant continuing part of his work has been the provision of training courses and software to assist Approved Test Houses with the certification of metering installations.
Keith has been technical expert or peer reviewer for many IANZ accredited laboratories in New Zealand and as a technical peer reviewer for national metrology institutes in the Asia-Pacific region.
The Course is Suitable For:
Industry staff in the Class A and Class B Meter Test Houses and people who are involved in the metering and measurement, and the buying and selling, of power in New Zealand.
General Programme and Learning Outcomes
Day One is designed to give all staff in the approved test houses an understanding of the technical side of their laboratory’s operation. It will also include advice specific for class B approved test houses on managing uncertainty from design to installation (Technical Guide 33 – Electricity Metering: Advice for Class B Approved Test Houses).
Day One Program
- Introduction - why the emphasis on traceable measurement?
- Part 10 of the Electricity Industry Participation Code – An overview of the key points
- Energy meters - the factors that affect their accuracy
- Calibrating energy meters
- Measuring transformers - the factors that affect their accuracy
- Calibrating measuring transformers
- Basic statistics - making sense of errors and corrections, expanded uncertainty, and confidence levels
- Advice for class B approved test houses, managing uncertainty
- Comparative recertification
- TEEM Social Function
Day Two goes into more depth and is particularly relevant for staff who need to understand their laboratory’s measurement uncertainties in detail.
- The end-use of calibrated meters and measuring transformers; a demonstration of site certification using the MSL-developed MIEcalculator
- Laboratory calibration including calibration intervals, laboratory environmental control, and calibration of test benches
- Interpreting IEC standards and manufacturer’s specifications for energy meters and measuring transformers
- Metrology verification of new technology - understanding transformer analysers
- Uncertainty calculations for energy meters and measuring transformers - CMCs and your calibration certificate uncertainties.
- Site certification
- Hands-on use of the MIEcalculator to calculate site error and uncertainty
- Wrap-up discussion, course validation and certificate presentation
Course Qualification: Students will receive a course attendance certificate.
Preparation: Students who attend day two are encouraged to bring specifications for a particular meter or metering installation that can be used as a worked example. Students will require laptops to gain hands-on experience of the software being demonstrated.
