Overview

The DDX 9161 is a laboratory optimized, highly integrated, versatile PD and RIV detector, accommodating up to four simultaneous PD/RIV and Voltage inputs. It is a fully digital state-of-the-art high-performance PD detector. The DDX 9161 is modular and fits a wide range of PD detection applications. It includes an integrated low-noise power supply together with rugged fiber optic connectors and follows the Haefely “plug & forget” concept. Conventional partial discharge measurements according to the latest IEC 60270 or RIV measurement according to the NEMA and CISPR standards are covered. Phase Resolved PD (PRPD) analysis and Data Logger function are possible as well. Multiple units (maximum 12 channels) can be connected in daisy chain communicate with a Control Software, which handles data acquisition and display PD information, test results and generates reports. The DDX 9161 increases the laboratory sensitivity as it is equipped with the most flexible digital filters available on the market allowing the measurement frequency band to be shifted into a less noisy range and suppressing frequency-dependent noise. The reports can be printed or saved to PDF. The software also provides screenshots function for inclusion in other reports. A default report template is included. However, any new template can be provided on request (option).
