HV TECHNOLOGIES, Inc. provides you with accurate and reliable systems for partial discharge measurements of HV equipment such as transformers, generators, switchgear and cable systems in laboratory or on-site environments.
The DDX 9160 (battery operated) and DDX 9161 (lab-optimized) are the newest PD detectors from Haefely for AC, DC, and RIV partial discharge measurements. The fully digital state-of-the-art detectors can accommodate up to four simultaneous PD/RIV and Voltage inputs. The modular design fits a wide range of PD detection applications. Conventional AC & DC PD measurements according to IEC 60270 or RIV measurements according to NEMA and CISPR standards are covered. The device can be mounted on a coupling capacitor and fiberoptic cables provide galvanic isolation from the HV test floor to the control room, ensuring the highest safety level for operating personnel. The measuring impedance can be integrated into the detector to reduce the number of components required for successful PD measurements.
This high resolution stand-alone PD detector can be used for various PD testing applications according to IEC 60270. There are 3 versions available:
- HTP-2/D – alphanumeric LCD is situated on the front panel of the detector showing the measuring values in pC and the frequency of the applied test voltage.
- HTP-2/W – measuring data access is given via web browser with calibration, test voltage, charge, and various diagrams.
- HTP-2/S – PD detector is supplied with HVT Software Suite for PC operation and with advanced functionality with recording of tests and replay of results.
