1 - 14
• Power transformer testing (TR)
– ratio and polarity / tap changer test
– measuring winding resistance
– testing tap changer contacts
– dielectric withstand voltage test (2kV AC)
• Resistance testing
– measuring contact resistance (µ
Ω
)
– measuring winding resistance (µ
Ω
- k
Ω
)
– measuring earth resistance (µ
Ω
- k
Ω
)
– dielectric withstand voltage test (2kV AC)
• Other applications
– Ramping , a pogrammable ramping generator and determination of
thresholds
– Sequencer for automatic testing with different states in real time
– Comment card to hold a user-defined comment and/or note regarding the
actual test procedure.
– When using the Amplifier test card, an input signal fed into a
synchronization input drives the high-current output’s magnitude,
frequency and phase angle.
• Insulation tests (TanDelta)
CP TD1 for on-site insulation tests of high-voltage systems like power and
measuring transformers, circuit breakers, capacitors and isolators.
• Automated testing of each application via front panel control
• Automatic report generation: test results are automatically recorded and
saved together with the test card
• CPC 100 can be connected to an external PC via an Ethernet connection.
This way, test reports, for example, can be loaded onto this PC and
customized in standard applications.
• CPC 100 provides a "dead man" function, that is the possibility to install an
additional push-button that stops remote operation if released (refer to ”ePC
Interfaces” on page 2-4).
Any other use of CPC 100 but the one mentioned above is considered improper
use, and will not only invalidate all customer warranty claims but also exempt the
manufacturer from its liability to recourse.
