CP TD1
CP TD1 - 7
In addition to the Dissipation Factor (TanDelta)/Power Factor test, the CP TD1 can also be used
as a high-voltage source for measuring, for example, partial discharge or conducting high-
voltage tests on rotating machines.
To compensate capacitive currents, a parallel resonance circuit can be set up.
The compensation using the CP CR500 compensation reactor is realized in two different ways:
First, by parallel circuiting the compensation reactors to measure as close as possible to the
resonance frequency when measuring with nominal frequency is required. Second, by setting
the frequency to measure at exactly the resonance frequency. The longest output duration is
achieved with testing at resonance frequency, in most cases accomplished by a combination of
both procedures.
The CP TD1 High-Voltage Source test card can be used both for manual or fully automatic
testing by toggling defined ramps and sequences. The test card is also helpful in setting up the
optimum test configuration to achieve the best possible test duration.
Typical Test Procedure
• Without compensation
If the capacitance of the test object is smaller than 80 nF (up to 12 kV and ton > 2 min.), no
compensation is required.
• With compensation
1. Determine the capacitance of the test object
2. Calculate the inductors needed for the compensation
– manual calculation
– by using the CP TD1 High-Voltage Source test card
3. Set the test voltage
4. Set ftest (manually or with Search f0…)
5. Start the test (define test cycle before, if required)
