Sweep Frequency Response Analyzer

The M5500 Sweep Frequency Response Analyzer is our newest generation of SFRA diagnostic instrument. With incredibly fast sweep speed and expanded dynamic range, you can use the Doble M5500 test set to investigate mechanical integrity of transformers, reactors and other equipment with windings. Coupled with the ease-of-use and powerful features of the new SFRA 6 Software, conducting SFRA testing and analysis of your apparatus has never been easier or more productive.

High Voltage Asset Analyzer

The only test set featuring two dual-function high-voltage leads for source and measurement delivers the fastest, complete set of measurements. Compared to a single-lead system, this patented design dramatically improves technician safety by reducing ladder trips by as much as two-thirds and simplifying lead placement.

The M7100 automates multiple tests, previously performed by several pieces of equipment, cutting down testing time from seven hours to one and a half hours. Reduced testing time means technicians can safely perform more commissioning, scheduled maintenance and diagnostic activities.

Condition Monitoring Platform for Transformers

The doblePRIME™ Transformer Condition Monitoring System gives you a clear, consolidated means to assess overall transformer condition.

Now you can pick the appropriate level of condition monitoring for an individual transformer or group of transformers in one location.

doblePRIME is a scalable, on-line monitoring solution. It can be as simple as one diagnostic device such as the Morgan Schaffer Calisto for DGA. It can also be a robust system monitoring and analyzing oil status, tap changer condition, bushing health, while integrating all types of diagnostic indicators, IEDs and sensor data. View this critical information on site or remotely.

doblePRIME can also integrate into an asset risk management system.

Westco Electrical and Equipment Corp. provide Insulation Oil laboratory services to the electric power industry. Westco’s  labs perform operations like: Dielectric Breakdown Voltage, Dissolved Gas Analysis, Corrosive Sulfur Test, Furan Test, Moisture in Oil, and Oil Quality. Our Insulating Oil Lab is headed by a Registered Chemist to assure quality testing and interpretations in accordance with standard.

When you need to manage asset risk across a fleet or on a problem transformer, Westco Electrical and Equipment Corp. provides an independent, expert opinion enabling critical decisions to be made with confidence. Westco’s transformer engineers have extensive transformer fleet health assessment and forensic analysis consulting experience as well as specification writing, factory audit, design review, factory inspection & test witnessing when purchasing new transformers.  We can also provide the full range of off-line electrical and in-services tests.
