A portable, multi-channel partial discharge (PD) monitor designed for HVPD, enabling advanced electrical asset condition monitoring in the field.

The Multi™ Portable Monitor has empowered engineers to carry out comprehensive PD testing and asset diagnostics on-site, supporting proactive maintenance and improved reliability for high-voltage equipment.

HVPD needed a portable device that could deliver laboratory-grade PD monitoring in a rugged, field-ready package. The design had to accommodate multiple channels, provide clear data feedback, and withstand the rigours of on-site use in challenging environments.

4D Products collaborated with HVPD to develop a robust enclosure and user interface for the Multi™ Portable Monitor. The team focused on ergonomics, durability, and ease of use, creating detailed CAD models and prototypes to refine the design. Special attention was given to the integration of connectors, displays, and controls to ensure reliable operation and straightforward deployment in the field.

The finished Multi™ Portable Monitor delivers advanced PD monitoring capabilities in a compact, portable form. Its thoughtful design supports HVPD’s mission to provide innovative, practical solutions for electrical asset management and condition monitoring.
