PD Surveyor with EMI Capabilities The PDS200 Surveyor is a partial discharge surveyor tool with EMI capabilities. It identifies and analyzes radio frequency (RFI) and lower frequency electromagnetic (EMI) emissions. These are associated with faulty or degraded insulation and other system defects. The PDS200 uses EMI analysis to discriminate between different defects and discharge sources […]

Partial Discharge Surveyor The Doble PDS100 Partial Discharge Surveyor is a radio frequency interference (RFI) surveying tool that is designed for partial discharge measurement in a live substation. Without the need for outages, the PDS100 can detect partial discharge (PD) in just a few seconds – making it an ideal tool for a condition based […]

Portable Dissolved Gas Analyzer To make informed decisions on site, you need fast and reliable data. Myrkos portable gas analyzers provide laboratory quality DGA data where you need it, when you need it. In remote locations, to confirm monitoring data, or whenever on-site diagnosis is required, Myrkos portable gas analyzers provide results as accurate as […]

Leakage Current Monitor The Doble LCM500 Leakage Current Monitor can measure condition while a surge arrester is still in service, measuring the quality of the metal oxide blocks and helping manage the risk of failure. A surge arrester may be inexpensive, but it has an important role in protecting your transformers. With the LCM500 surge […]

For Rotating Machine & Power Plant Applications Doble’s EMI Surveyor is an in-service, EMI testing solution that can identify more than 70 different electrical and mechanical defects in generators, motors, bus duct and other high-voltage (HV) electrical plant equipment. The EMI Surveyor measures the release of electromagnetic (EMI) energy resulting from HV electrical insulation-related partial […]

Portable Moisture in Oil and Dewpoint Analyzer The Doble DOMINO USS (Ultimate Sampling System) gives you a fast, efficient way to measure water content in oil and/or the dewpoint of a gas. The DOMINO USS is a portable system that connects quickly and easily to transformer valves or other oil-filled electric devices. Operating on AC […]

RFI & Acoustic Signal Surveyor Use the Doble DFA300 to identify and locate insulation defects. This surveying tool combines radio frequency interference (RFI) and acoustic emission (AE). The DFA300 partial discharge detector can locate partial discharge (PD) in a few seconds. Designed for surveying live, high voltage apparatus, its versatility makes it the perfect, multi-purpose […]

Dielectric Fault Analyzer The DFA100 Dielectric Fault Analyzer is a handheld survey tool used to identify and locate partial discharge, particles, and mechanical defects. With three measuring modes, continuous, phase and pulse, the DFA100 uses its acoustic emission sensor to find in-service acoustic signals produced by partial discharge and loose components. As an option, the […]
