Solution

Schneider Electric PME

Transpower operates New Zealand’s high-voltage national grid, connecting generation sources with cities, towns, and major industrial users across the country. Reliable and accurate metering across grid exit points (GXPs) is critical for settlement, operational analysis, and system transparency.

To support the modernisation of its revenue metering infrastructure, Transpower undertook a nationwide upgrade program to replace legacy meters installed across substations throughout New Zealand

The Challenge

Many of the legacy revenue meters installed in the early 1990s were reaching the end of their operational life and lacked the capability required for modern grid analytics and power quality monitoring.
Transpower required a solution that could:

Replace ageing metering infrastructure across multiple substations
Provide high-accuracy revenue metering
Capture power quality and event data
Integrate seamlessly with existing SCADA and operational systems

The Solution

Quasar worked with Schneider Electric technologies to deploy PowerLogic ION8800 rack-mounted meters across the national grid.
These advanced meters provide high-accuracy revenue metering combined with extensive monitoring capabilities including:

Voltage excursion monitoring
Power factor and frequency analysis
Power quality monitoring
Integration with existing SCADA and enterprise systems

Technology Used

Schneider Electric PowerLogic ION8800 meters coupled with EcoStruxure Power Monitoring Expert (PME). This solution provides the data required for capacity planning, stability analysis, regulatory compliance and energy settlement
‍
The platform allows facility managers to:

High-accuracy revenue metering
Power quality monitoring
Event recording
Integration with grid data systems

This allows Transpower to capture detailed operational data from GXPs across the network and analyse events affecting grid performance.

Measured Outcomes

Accurate revenue metering across the national grid

Detailed visibility of voltage excursions and network events

Faster analysis and communication of grid incidents

Improved integration with Transpower’s operational systems

Platform Behind the Results

PowerLogic ION8800 revenue meters

The solution is powered by Schneider Electric’s PowerLogic ION8800 revenue meters, deployed across Transpower grid exit points. These advanced meters deliver high-accuracy revenue measurement while capturing detailed electrical and power quality data.

With high-resolution monitoring and event recording, Transpower engineers gain greater visibility of grid performance and the ability to quickly analyse network disturbances across New Zealand’s transmission network.
