How to apply DAC on HV cable systems:
This method provides system operators with a
lightweight, small and easy to apply technology. All
parts of the DAC MV30 test equipment can easily be
covered with flight case and fit into a car/ small van
with a cargo load below 100kg. The application takes
approx 2 to 3 hours:
1. |
DAC MV30 system assembly on site
(1/4 hour) |
2. |
Connection of all parts and checking of
system (1/4 hours) |
3. |
Testing and measurement of all three phases
of a system (1.5 hours) |
4. |
Analysis of the measuring results -
disconnection and packing of test system into
transportation boxes (1 hour) |
Main advantages:
|
Low energy consumption on site – small
footprint for test equipment |
|
Only one engineer is needed to execute the
full test |
|
Cable system shut-down time will be minimized
to 2…3 hours |
|
Voltage withstand test automatically
monitored by partial discharges |
|
Results of non-destructive and sensitive PD
measurement and tan δ are available on the
same day |
|
This approved testing methodology is in
accordance with relevant international
standards and recommendations (IEEE, IEC,
CIGRE) |
