Three‑Phase Electricity Meter Aging Test Bench for Smart Meter Reliability
This reliability-tested electrical tester has been specifically designed to test thousands of three-phase multi-function smart meters for overall quality and endurance in high-volume applications. The tester uses the ZN-D3000 precision power supply to provide consistent voltage/current loads to simulate long-term field usage and to maintain measurement accuracy and structural integrity during ongoing static load. The tester is designed to support multiple simultaneous aging processes using modular connectors mounted on the vertical meter rack, making it an extremely high-density testing solution.
As part of its ongoing measurement process, the system tracks any changes in key indicators: such as dielectric strength, register accumulation (walking test) and communication protocol (IEC 62056 – 21, DLMS/COSEM) stability. The control interface can be used to adjust phase angle, harmonic distortion and load levels more precisely. Real-time data logging and automatic trip protection allow safe testing and historical records to be maintained over a 24/7 testing period. This robust testing regimen meets or exceeds International (IEC, ANSI) testing standards and guarantees 15-year service life under extreme conditions. By improving electronic devices’ rate of infant mortality, the bench provides long-term billing accuracy.

What is an Electric Meter Aging Test Bench?
An Aging Test Bench for Electric Meters is designed to perform accelerated life cycle (burn-in) testing of single-phase and three-phase energy meters using controlled voltages and currents under established environmental conditions (room temperature). By applying the rated voltage and current over an extended time (hours to days), early failures in electronic components, solder joints, and mechanical parts can be identified. A test bench is used with a high-precision programmable power supply (e.g., ZN-D3000), a high-density meter mounting rack with modular connectors, and data logging software. The test bench collects data for walking tests (i.e., register accumulations), communicating stability, and dielectric strength during the aging cycle of the meter. The Aging Test Bench System will also help to lower the infant mortality rate of smart meters and will ensure compliance with IEC 62053-11/22, ANSI C12, or specific customer reliability requirements. As a non-standard, custom solution, this system will be tailored to your specific meter form factor, number of positions (e.g., 24, 48, 96 meters), and communication protocols.
Synchronized three‑phase voltage & current, adjustable amplitude, phase, and harmonics.
Modular connectors for simultaneous testing of multiple meters (24‑96 positions).
Dielectric strength, register accumulation, communication protocol stability.
Overload, over‑temperature protection; CSV/MES export for traceability.

핵심 기술적 이점
High‑density parallel aging reduces cycle time
With up to 96 meter positions, the bench significantly accelerates burn‑in testing. Each position is independently monitored, allowing batch qualification without reducing throughput.
Precision ZN‑D3000 source for realistic grid simulation
The integrated power source delivers synchronized three‑phase voltage and current with adjustable phase angles, harmonics, and load levels. This simulates real‑world grid disturbances (voltage sags, harmonics) that affect meter performance.
Comprehensive communication & register monitoring
The bench reads meter registers via RS485 or optical port during the aging cycle, verifying that the accumulation remains accurate under continuous stress. Communication errors are logged for protocol stability analysis.
Automatic safety & data traceability
Real‑time trip protection prevents damage from meter failure. All test data (voltage/current logs, register values, error events) are saved and can be exported to MES or CSV, providing full traceability for ISO 17025 audits.
Customer Success Story – Smart Meter Manufacturer
A major manufacturer of smart meters required reduction of the field failure rate of their three phase meters due to electronic components failing early in their life cycle (infant mortality). In response to this need, Benlong provided a 96-position meter ageing test bench outfitted with a ZN-D3000 power supply and real time register monitoring equipment. Six months after the installation of these test benches:
Within less than 10 months after installation, the customer was able to benefit from the bench’s cost savings by securing a significant utility contract which required compliance with IEC 62053-22 standard.

자주 묻는 질문
Aging tests, based on a specified voltage and current rate, are applied to meters over a long period of time, like 24 to 72 hours, to identify electronic components (such as capacitors, power supplies, or solder joint connections) that are prone to failure in the field, thus helping reduce infant mortality and guarantee a long useful life of new products.
At regular intervals (hourly for example), the bench will obtain meter register reads via an RS485 or optical port and compute an accumulator for those meter registers to compare against a reference value for drift or communication errors (known as a “walking test”).
Definitely! Both single-phase and three-phase meter configurations will be available; this includes single-phase connection configurations utilizing single-phase power and three-phase connection configurations utilizing ZN-D3000 three-phase source configuration. Backup racks can be created, however they will require separate wiring.
The device can connect using RS485 (Modbus RTU, DLMS/COSEM), an optical port (IEC 62056-21), pulse outputs, or optionally wirelessly (LoRa, NB-IoT). Custom integrations can be made with the device.
Each meter position has an individual circuit breaker or fuse for failure isolation along with overload protection (current limitation), over-temperature shutdown, short circuit detection and ground fault protection.
