Testing with the ZGX Series Regenerative 15 kVA AC-AC+DC Source and Load

ZGX series power supply
In the ever-evolving field of electronics, the need for precision and reliability in testing equipment has never been greater, and engineers understand that the quality of their tests is directly linked to the quality of their equipment. The BriPower ZGX Series Regenerative AC-AC+DC Source and Load offers a standard 4U rack solution capable of delivering 15 kVA for comprehensive converter testing. Multiple units can be slaved together to scale test solutions to 960 kVA.

ZGX series power supply

Compact 4U Rack

One of the most significant advantages of the ZGX Series is its 4U standard 19” form factor. Traditional test setups with this level of power would often require multiple pieces of equipment. The ZGX Series condenses this power into a single, efficient 4U rack unit, simplifying the setup and maintenance of the testing environment.

This space-saving design not only enhances efficiency but also saves valuable lab real estate. The convenience of this 4U rack standard means engineers can focus more on their testing objectives and less on managing bulky equipment.

Versatile Regenerative Functionality

Regenerative capability is a key feature of the ZGX Series. Unlike conventional power supplies that would require some way of dissipating excess energy as heat, normally in a dump resistor, regenerative power supplies recover energy and feed it back into the grid. This feature is invaluable for testing energy-efficient systems, reducing operating costs, and minimising environmental impact.

Testing Setup, Precision and Reliability

The ZGX has built in options for battery simulation, photovoltaic cells (PV), and advanced powerline simulation for aerospace standards. A built in system for defining the source impedance of the power supply adds powerful simulation and validation possibilities, and the new RCD option allows for diode behaviour to be emulated in the ZGX output. With a highly stable output voltage, advanced programming capabilities it provides the control required to test a broad spectrum of electronic components and systems.

Contact PPM Power

Protecting Electrical Apparatus with Corona Detection

UVolle handheld corona detection camera
Corona and partial discharge on power distribution lines needs to be quickly detected and pin-pointed, so maintenance teams can perform timely preventative maintenance and avoid costly unplanned blackouts.

What is partial discharge and corona?

Corona discharges, detected using UV cameras, can indicate potential equipment failure due to various factors such as insulation damage, inadequate clearances, or faulty installations.

Corona detection

Why is it important?

Identifying these issues early can:

  • Prevent unexpected power outages
  • Ensure safety
  • Increase service reliability
  • Boost customer satisfaction

The Benefits of Using Ofil’s DayCor® Camera

Ofil’s partial discharge inspection cameras are designed for daytime investigation of electrical apparatus indoors and outdoors. Their DayCor® technology features very high sensitivity to corona signals and perfect signal positioning to pinpoint the discharge exactly. Alternative technologies can only indicate the presence of corona and partial discharge with a limited resolution, meaning the exact location is unknown.

UVolle handheld corona detection camera

The handheld cameras are ideal for remote testing of high voltage apparatus; they are light-weight, provide details on humidity and temperature, include a screen, and the ability to save to an SD card.

The gimbal and fixed mounted cameras, alternatively, can be mounted on electric trains to monitor rail infrastructure, or on drones and aerial systems allowing for remote monitoring of difficult to access areas. These corona cameras are ideal for systems integration.

Regular inspections using these UV cameras can identify faults before they escalate to system failures. This preventative approach:

  • Allows you to move from corrective to predictive maintenance
  • Increases worker safety through remote, non-contact inspections
  • Extends the lifespan of your equipment
  • Saves costs associated with major repairs or replacements
  • Enables inspections in hard-to-reach areas.

These inspections can also be carried out without interrupting the power supply, keeping customer inconvenience to a minimum.
