GENY Successfully Delivered a 32-Position 160A Smart Meter Test Bench to CLP Power Hong Kong Limited
2026-04-19
In 2024, Guangzhou Geny Electric Ltd successfully delivered a 32-position, 160A, Class 0.02 three-phase smart meter test system to CLP Power Hong Kong Limited (“CLP”), one of Hong Kong’s leading power utility companies.
This project marks the first successful deployment of GENY’s classic 160A meter test bench at CLP, representing an important breakthrough for GENY in the Hong Kong utility market. It also demonstrates our capability to provide high-precision, utility-grade meter testing solutions for demanding international applications.
As a major power company in Hong Kong, CLP maintains strict requirements for accuracy, safety, compatibility, reliability, and compliance with local standards. The successful implementation of this project reflects GENY’s strong expertise in smart meter testing systems, isolated current solutions for closed-link meters, automated testing, and customer-oriented engineering customization.
Project Background
With the ongoing development of smart grid infrastructure, utility companies require more from meter test equipment than conventional accuracy verification. Modern test systems must also support:
l Smart meter communication and function testing
l High-efficiency multi-position parallel testing
l Compatibility with different meter structures
l Testing of closed current link / IP-link smart meters
l Harmonic and influence quantity testing
l High-accuracy calibration in accordance with IEC standards
l Compliance with local safety and wiring requirements
For CLP, the solution needed to combine high measurement accuracy, practical operation, smart meter communication capability, and adaptation to Hong Kong standards. Based on GENY’s mature platform and engineering experience, we delivered a tailored configuration of the YC1893D-32-0.02-F three-phase smart meter test system.
The Solution
The delivered system includes the following core modules:
l Three-phase static power source
l Three-phase reference standard meter
l 32-position meter test rack
l Smart meter function test system
l Optical probes and scanning heads
l Quick Connector Devices (QCDs)
l Isolation Current Transformers (ICTs)
l PC software and system control platform
l Serial communication expansion system
The system supports single-phase and three-phase meter testing in automatic, semi-automatic, and manual modes, and is suitable for:
l Electronic energy meters
l Electro-mechanical meters
l Smart meters
l Closed-link / IP-link meters
l Different terminal layouts and meter designs
Key Highlight 1: 32 Positions for Efficient Parallel Testing
The project includes two test racks with a total of 32 meter positions, enabling efficient parallel testing for batch inspection and calibration.
Each rack is constructed with aluminum alloy structures, combining strength, corrosion resistance, and mobility. The rack design also supports easier installation, maintenance, and layout adjustment in the customer’s working environment.
Each meter position is equipped with:
l QCD quick connection device
l Scanning head and optical probe
l Error LED display with inputs
l Metercommunication readout (dlms/kingfisher)
This configuration allows the system to perform not only conventional accuracy tests, but also smart meter communication and function verification.
Key Highlight 2: 160A Output with ICTs for Closed-Link Meter Testing
One of the major technical requirements of this project was support for high-current testing up to 160A, while also ensuring compatibility with closed current link smart meters.
To meet this requirement, GENY integrated high-precision Isolation Current Transformers (ICTs) into the system. These ICTs provide isolated and potential-free current signals, allowing reliable testing of meter types that are difficult or impossible to test on conventional benches.
Main ICT features include:
l Current range: 3 × (10mA – 160A)
l Accuracy class: 0.01
l Ratio: 1:1
l Frequency range: 45Hz – 65Hz
l Output power: 3 × 70VA max
This solution significantly extends the test bench’s compatibility with modern smart meter designs and enhances its long-term application value.
Key Highlight 3: High Accuracy and Stable Performance
The system delivered to CLP provides Class 0.02 performance, enabled by GENY’s stable three-phase power source and high-accuracy reference standard meter.
Power Source Performance
l Voltage output: 3 × (5V – 456V)
l Current output: 3 × (1mA – 160A)
l Setting accuracy: better than 0.05%
l Stability: better than 0.005% / hour
l Distortion factor: < 0.3%
l Harmonic output: 2nd to 51st programmable
l Phase angle range: 0° – 360°
l Frequency range: 45Hz – 65Hz
Reference Standard Meter Performance
l Voltage measurement range: 5V – 480V
l Current measurement range: 10mA – 160A
l Voltage, current, power, and energy error: ≤ ±0.02%
l Multiple wiring modes supported
l Harmonic measurement and waveform display supported
This configuration ensures the system can meet demanding utility and laboratory requirements while maintaining reliable long-term performance.
Key Highlight 4: Flexible Operation for Real-World Utility Applications
To support different working scenarios, the system is designed for:
l Fully automatic operation
l Semi-automatic operation
l Manual operation
The power source cabinet is equipped with a touch panel / VFD keyboard for convenient local control. At the same time, RS232 and Lancommunication interfaces allow automated control through PC software.
The system supports a wide range of test items, including:
