Doble
Products & Services for Partial Discharge (PD) Detection
and Monitoring
|
|
| Doble
now offers a complete line of partial discharge monitoring and
analysis test equipment. A thorough condition-based maintenance
program should include a selection of tools for continuous on-line
monitoring and detection of Partial Discharge (PD) in HV apparatus.
Following the initial detection of PD, the results can be further
verified by high precision off-line techniques and appropriate
corrective action taken.

FailSafe
LF & Capacitive Couplers
Doble offers a variety of capacitive
couplers that allow for decoupling of PD signals from
various electrical sources.
Featured is the FailSafe LF Coupler.
This coupler allows for continuous online monitoring
of rotating machines at lower frequencies than traditional
HF couplers.
Lower frequencies allow for the whole stator to be monitored,
not just the first few coils.
In addition, the unit does not compromise the reliability
of the system by incorporating a fused element that
safely removes the coupler in the event of a failure.

TransformerGuard(for
Transformers) PD Monitoring System
TransformerGuard is a solution
for monitoring PD activity in transformers.
It is equipped with a PD-Guard/UHF that allows for the
connection of various UHF sensors that can be either
mounted through tank hatches or inserted through an
oil drain valve.
UHF technology allows for detection of PD activity deep
within transformer windings without attenuation.
Doble’s experts will assist you in analysis.

TerminationGuard(for
Cable Terminations) PD Monitoring System
TerminationGuard is a condition
based monitoring system for assessing the condition
by cable terminations in the field.
Once installed in the field, the most likely place for
a cable to fail is either at splices or terminations.
TerminationGuard targets the terminations and can reliably
assess their condition by using the latest in UHF PD
based technology.
By monitoring the in-service partial discharge, the
insulation performance can be monitored over time and
corrective action can be taken before a failure occurs.
