Products & Services

Biddle Partial Discharge [Corona] Detectors are quality instruments that will provide long-term service, if properly maintained.  We have the capability to provide this maintenance.  HV Test Technology has a large stock of hard-to-find parts for Biddle Partial Discharge [Corona] Detectors of all ages [ca. 1976-2004] including Catalog Numbers 17000, 27000 and 37000, in addition to 6617250 series Master Calibrators.  Our stock of parts permits us to repair all of these instruments quickly and at reasonable costs.  We can restore oscilloscope displays.  We can upgrade Calibrator rise-times to meet IEC 60270 requirements.  We can update transient voltage spike protection in older detectors.

We can also supply new PD test system components including [contact us for details]:

• Precision Low Voltage Calibration Couplers.
• Calibration Signal Generators for use with any make or model PD Detector.
• Bridge Coupling Units to increase test system sensitivity.
• Power Separation Filters. 
• PD Signal Counters for use with 17000, 27000 & 37000 Detectors.
• High Voltage Transient Surge Limiters.
• Replacement tubes for Biddle Cable Termination Systems. 

In addition, we can provide on-site services to help solve troubleshooting and repair problems, interference problems, grounding problems, transient voltage spike problems, test fixture problems and provide operator training, when Test System Instruction Manuals have been lost.
