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. It is designed for simple operation and
rapid measurement. For production applications, the system has a “locked” mode, which password
protects all settings that could affect the system operation.
The system emulates the look and feel of a traditional analogue PD detector making it easy for users to
make the transition to the new system. It is designed to be compatible with Tettex, Haefely and Robinson
detectors, making it easy to upgrade an older detector to the new system.

1.3. Connection To The Mains
The mains connector for the instrument is located on the rear panel. It uses an IEC-320 standard
connector. The input is auto-sensing and can be on any supply whose voltage is between 85VRMS to
264VRMS and whose frequency is between 47Hz and 440Hz. Operation on supplies outside this voltage
range will require the provision of a transformer to bring the voltage into the specified operating range.
Operation outside the specified range of frequencies is not possible
Connection of the system to a supply voltage outside its operating range will
result in damage to the system along with the risk of injury and fire

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. The installation of a PD measurement
system requires an understanding of the mechanisms of PD measurement.
It is recommended that the HV system is provided with a low impedance ground/earth that is separate to
the main building earth system and has an impedance less than 1Flat braid or flat copper strip should
be for all ground/earth connections to minimize the effects of skin effect.
The case of the DDX-9101 is designed to be connected to the HV earth. It is linked to the mains earth via
a 300H choke and a varistor (for protection). If this conflicts with other grounding/earthing requirements,
it will be necessary to provide additional isolation to the system. Advice on this can be obtained from the
local agent or from the manufacturer.
FOR CONTINUED OPERATOR PROTECTION: The ground/earth connection in the
mains socket or the case of the instrument MUST be connected to a suitable
protective ground/earth. If this is not done there is a significant safety risk for the
operator in the event of a system or sample failure.
2.2. Rear Panel Connectors
Figure 2.1 shows the rear panel connectors of the DDX-9101.
Figure 2.1 –Rear Panel Connections
The Mains connection (1) must be connected to a suitable rated source of power. It carries the protective
earth connection. This must be connected to a suitable protective earth, otherwise there is a safety risk
for the operator.
The “System Earth” (2) connection must be connected to the main HV ground/earth point using a suitable
braid or copper foil connection. See the connection details for more information on this connection. For
continued protection of the system and the operator it is imperative that this connection is made, or an
equivalent provision is made.

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. If the DDX-9101 is to be connected to a factory network or to a PC running on a
different mains supply, a suitable fibre optic isolation system should be used.
The PD Input (4) picks up the discharge pulses from the input unit, power separation filter or quadripole.
This input is grounded to the case of the unit. If galvanic isolation is necessary, advice from Hubbell High
Voltage Test or its authorised agents must be sought.
The VM input (5) connects to the HV divider to allow the DDX-9101 to measure the applied HV. It also
uses this input for synchronisation, so the divider output must be AC. The input is grounded with respect
to the system ground and no common mode voltage can be tolerated between the two, either in
continuous operation or under transient conditions.
The calibrator output (6) is only available if the internal calibrator option is installed. It provides a step-
wave output of up to 10V pk. When combined with a calibration injection capacitor that has been certified
in accordance with IEC-270, it forms the basis of an IEC-270 compliant calibration source. The calibrator
is galvanically isolated from the rest of the system, though the common mode voltage between the
calibrator and the rest of the system must be less than 35V.
2.3. Connection to Tettex 9230 coupling capacitor with AQS 9110a
Figure 2.2 Connection to Tettex 9230 coupling capacitor with AQS 9110a
The AQS 9110a advanced quadripole is a fully configurable quadripole system for use with partial
discharge detectors. To allow the system to be optimised for specific application and different test area
conditions, there are a whole range of selections available at commissioning. The quadripole has a
voltage divider low-arm fitted to it. This is a three range switchable unit that gives control of the division
ratio. This can be configured for specific applications during ordering. Ensure the selected ratios are
correct before using the low arm on your system. The AQS 9110a is operated as a fully passive
measurement system with enhanced sensitivity.
