The DDX 9161 is the newest laboratory optimized PD detector from Haefely for AC, DC, and RIV partial discharge measurements. The fully digital state-of-the-art detector 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.
Haefely’s CaMS software platform provides the most modern, flexible, and user-configurable PD application software on the market. The software enables the controlling of single channel, multi-channel (up to 4 channels per unit) and/or multi-detectors (connected in a daisy chain). A dark mode display includes all the required PD analysis tools such as information display, pulse diagram, PRPD pattern (fingerprinting), data logger, and more. The number of meter indicators, as well as their size, can be selected. Reports can be easily created in pdf format.
Rugged fiberoptic cables provide galvanic isolation between HV test floor and the control room, ensuring the full safety of the operating personnel. Laboratory sensitivity is increased with the most flexible digital filters available on the market allowing the frequency measurement band to be shifted into a less noisy range and suppressing frequency-dependent noise.
