Axia acquired another CE‑6710: Expanding power system testing capability

Axia, a reference in services and engineering in the power sector, further expanded its technical capacity with the acquisition of another CE‑6710, one of Conprove’s most complete and versatile instruments for secondary-level testing. This purchase reinforced the company’s commitment to reliability, precision, and excellence in diagnostics and validation of protection, automation, and control systems.

The CE‑6710 stood out for combining multiple functions in a single portable instrument—ideal for both field and laboratory applications—meeting the most demanding requirements of electrical professionals.

The CE‑6710 is widely used to test, calibrate, and verify different types of equipment, including:

• Electromechanical relays
• Static relays
• Microprocessor-based (digital) relays
• Transducers
• Meters
• Power quality analyzers
• Circuit breakers (via oscillography)

Its high signal-generation accuracy makes the device ideal for applications that require absolute confidence in test results.

Equipped with 6 high-accuracy current channels and 4 high-accuracy voltage channels, the CE‑6710 enables a broad range of tests, including:

• Three-phase and six-phase testing
• Multifunction testing
• Simultaneous tests on multiple inputs
• Advanced applications in differential, directional, distance protection, and more

All control is performed via software, supporting both manual tests and automated sequences through virtual instrumentation.

The instrument uses DSP to generate highly faithful waveforms, enabling continuous frequencies up to 3 kHz. This enables:

• More stable signals
• Higher measurement accuracy
• Repeatable test results
• Advanced simulations for different scenarios

DSP flexibility makes the CE‑6710 an essential tool for modern protection and measurement testing.

One of the CE‑6710’s key differentiators is its full support for IEC 61850 and IEC 61869, both critical for digital substations and Ethernet-based systems.

The instrument enables:

• Sending and receiving GOOSE messages
• Publishing and subscribing to Sampled Values (SV)
• Testing any protection function that uses GOOSE
• Comparing operating time between traditional actuation (dry contact) and digital messages
• Evaluating differences between analog signals and SV

This ensures users can test next-generation digital relays and IEDs with full precision.

Thanks to its robustness, accuracy, and versatility, the CE‑6710 is ideal for:

• FAT – Factory Acceptance Tests
• SAT – Site Acceptance Tests

Engineers and technicians can validate complete systems before energization and ensure compliance after installation—reducing rework and increasing reliability.

The acquisition of another CE‑6710 strengthened Axia’s ability to deliver high-performance services to the power sector. With this tool, the company expanded its capabilities in advanced testing, precise diagnostics, and safe commissioning—keeping pace with the technological evolution of conventional and digital substations.
