Core offering

Power Diagnostic Service develops, manufactures, and sells Partial Discharge monitoring hardware (the PDSimply integrated monitoring system, a broad PD sensor family covering UHF, TEM, Bushing, TEV, HFCT, AE, and Ultrasonic, plus the EZY-CUBE, EZY-CC, and PDProbe product lines) and delivers on-site professional diagnostic services for power infrastructure operators. Offerings target electric utilities, manufacturing, refinery, and transportation customers that operate high voltage equipment including transformers, cables, GIS (Gas Insulated Switchgear), switchgear, and rotating machines.

Product overview

Power Diagnostic Service (PDS) offers a portfolio of Partial Discharge (PD) monitoring solutions, sensors, and services for power system equipment. The core product is PDSimply, an integrated monitoring system for Transformer, Switchgear, Cable, GIS, and Rotating Machine applications. Supporting the monitoring platform are specialized PD sensors including UHF TM/TEM sensors, Bushing sensors, HFCT, AE sensors, and Ultrasonic sensors. The EZY product line (EZY-CUBE, EZY-CC) provides additional diagnostic capabilities. Services include Cable Testing, Fault Investigation, and Partial Discharge measurement services. The company operates globally with branch offices in Switzerland, US, Taiwan, Singapore, and Korea.

Broad incumbents

• ABB: Multinational power and automation company whose Electrification division supplies switchgear, transformers, and connected asset-monitoring solutions that overlap with PDS's diagnostic customer base.
• Siemens Energy: Global major in power generation and T&D equipment that offers condition monitoring and grid asset diagnostics as part of a broad portfolio, including services that compete with PDS at large utility customers.
• Qualitrol: Acquiring parent of IRIS Power, providing monitoring instruments for transformers, bushings, and switchgear, representing a broader portfolio competitor to PDS's instrumentation offerings.

Direct peers

• IRIS Power (a Qualitrol company): Specializes in partial discharge monitoring of motor and generator stator windings, plus transformer and bushing diagnostics — a direct competitor in PDS's rotating-machine and transformer PD segments.
• EA Technology: UK-based provider of condition monitoring, partial discharge testing, and asset management services for power networks, offering overlapping PD diagnostic products and field services similar to PDS.
• OMICRON Energy: Austrian-headquartered vendor of testing, diagnostics, and monitoring solutions for electrical assets, including PD measurement systems for transformers, GIS, and cables — competing head-to-head with PDSimply and related product lines.
• Megger: Long-established manufacturer of electrical test and measurement instruments for cables, transformers, and switchgear, including portable PD detectors that compete with PDS's portable diagnostic offerings.
• Doble Engineering: Privately held provider of diagnostic instruments and services for the electric power industry, with deep coverage of partial discharge testing, transformer insulation diagnostics, and on-site condition assessments — directly overlapping PDS's core PD monitoring business.
• HV Technologies (HIGHVOLT): Supplier of high-voltage testing systems, cable testing, and on-site diagnostic services, with overlap to PDS's cable testing and PD measurement service lines.

Regional players
