Both models are highly integrated, versatile PD and RIV detectors and can accommodate up to four simultaneous PD/RIV and Voltage inputs. They are fully digital state-of-the-art high-performance PD equipment.

The HAEFELY DDX 9160 & DDX 9161 partial discharge detectors are modular and fit a wide range of PD detection applications. DDX 9161 includes an integrated low-noise power supply together with rugged fiber optic connectors and follows the Haefely “plug & forget” concept. DDX 9160 can be operated by battery or use an external power supply. In addition, both units can accommodate four internal integrated measuring impedances up to 1 A covering most of the applications.

Conventional partial discharge measurements according to the latest IEC 60270 or RIV measurements 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 a daisy chain and communicate with a Control Software, which handles data acquisition and display PD information, and test results and generates reports.

The DDX 9160 and DDX 9161 increase 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.
