Key Considerations When Specifying Lightning Impulse Test Systems for Your Lab

Selecting the right lightning impulse test system requires careful evaluation of both current testing needs and future requirements. This guide outlines the critical specifications and design considerations to ensure your investment delivers long-term value while meeting IEC 60060 standards.

1. Voltage and Energy Requirements

Determine your system needs based on:

• Maximum test voltage: Typically ranges from 200kV to 6000kV

• Energy storage capacity: 5kJ to 200kJ depending on applications

• Future expansion: Modular designs allow voltage upgrades

• Standard compliance: Must generate 1.2/50μs waveforms per IEC 60060-1

2. System Configuration Options

Choose between these common configurations:

3. Control and Measurement Systems

Modern systems should include:

1. Digital control with intuitive interface

2. Automated waveform recording and analysis

3. Integrated measurement system meeting IEC 61083-2

4. Remote monitoring capabilities

4. Facility Integration Requirements

Consider these installation factors:

• Space requirements: Clearance distances for high voltages

• Power supply: Typically 50/60Hz, 3-phase

• Grounding system: Low-impedance ground mat essential

• Environmental controls: Temperature and humidity management

5. Compliance and Certification

Ensure your system meets:

• IEC 60060 series for high-voltage testing

• ISO 9001 quality management

• Local electrical safety standards

• EMC/EMI requirements

6. Lifecycle Considerations

Evaluate these long-term factors:

1. Maintenance requirements and costs

2. Availability of spare parts

3. Manufacturer support services

4. Training and documentation quality

By carefully considering these specification factors, you can select a lightning impulse test system that not only meets your current testing needs but also adapts to future requirements, ensuring maximum return on your investment while maintaining the highest testing standards.
