Page 7: Instrument Description
PD Detector DDX-9101 System Operation 1. Instrument Description 1.1. Introduction The DDX-9101 partial discharge detector is designed to replace traditional analogue detectors in those applications where the additional cost of a true digital discharge detector cannot be justified or where the complexity of measurement of such an instrument is not required. -

Page 9: System Installation
PD Detector DDX-9101 System Operation 2. System Installation 2.1. General Notes The correct installation of a partial discharge measuring system requires the balancing of two conflicting demands: the arrangement of the test circuit to maximise the measurement circuit and the arrangement of the test circuit to minimise the risk of damage from flash-over. -
Page 10: Connection To Tettex 9230 Coupling Capacitor With Aqs 9110A
System Operation PD Detector DDX-9101 The Network connector (3) provides connection to a 10BaseT Ethernet network utilising the TCP/IP protocol. If this is being used to connect to a single PC, the PC must be running on the same mains supply as the DDX-9101 and the two must be bonded together with a suitable braid ground/earth strap of less than 50cm length. -
Page 11: Connection To Tettex-Robinson Universal Quadripole System
PD Detector DDX-9101 System Operation A “Star” grounding/earthing scheme should be used for the system with the star point formed at the ground terminal of the Quadripole. Where the detector is being used with a power supply control system and is sharing a housing, it is recommended that steps are taken to prevent the formation of ground loops that could compromise the system performance and the flashover resistance of the system. -

System Operation PD Detector DDX-9101 2.5. Connection To Hipotronics PSF Systems Figure 2.4 Connection to Hipotronics PSF The Method if connecting the DDX-9101 to a Hipotronics PSF is shown in Figure 2.3. It is essential that the PSF used is of the PSFxx/y/DDX type (where xx is the rating in kV and y is the value in nF). If the PSF is not of the /DDX type (Part numbers PSFxx/y or PSFxx/y/700 for example) contact the Hipotronics factory for information on upgrading the PSF to the correct specification. - Page 13 PD Detector DDX-9101 System Operation determined from the “Max Current, Unbal.” column, the closest one with the required rating should be used: Tuning Capacitance Max Current.
