DIELECTRIC SYSTEMS Overview
INTERNATIONAL SALES MEETING 2009
Stefan Zimmermann
Intl. Sales Manager
PhenixAsia, Taiwan
Phenix Technologies manufactures a wide range of
Dielectric Test Sets from smallest kVA ratings in portables
to highest power ratings in the world.
Dielectric Test Sets are the best sold units of Phenix.
Dielectric testing is required, following applicable
standards of international institutions, for most electro
technical apparatuses and in our transmission/
distribution networks.
The most typical applications are:
Type testing
Routine testing
Acceptance testing
Preventative maintenance
Each facility uses its own test procedures and rules,
but all facilities are following certain standards
Most commonly known applicable standards are
IEC, IEEE, ASTM, AS, etc
A standard is a recommendation between the
standard committee and the end user
Dielectric Testing following IEC 4 and IEEE 60060.1
and 60060.2 standards define that the nominal
voltage x2 plus 1000V is to be applied for testing.
Un x 2 + 1000V
The maximum electric field that a dielectric can sustain
The voltage which an insulating material can withstand
before breakdown occurs, usually expressed as a voltage
gradient.
The electric voltage gradient at which an insulating
material is broken down or "arced through" in volts per
millimeter of thickness.
The value of a material as an electrical insulator or the
resistance to the flow of electric current.
What is a Hipot test?
We stress the insulation and measure the leakage current
in Amperes

Column type variable transformer (CTVT): The Phenix column type
variable transformer, designed for the purpose of controlling
output voltage offers following advantages:
Linear design (the contacts only move in a straight line)
Carbon roller contacts - Rolling friction is less than sliding
friction; therefore contact movement does not contribute to heat
build-up and does not accelerate wear. Rollers are spring-loaded
to ensure positive contact and to provide flexibility for movement.
Nickel-plated copper contact surface on the columns leads to
less wear and a longer service life. The commutating windings of
the CTVT are nickel plated in order to limit the circulating
currents developed when the carbon roller rests in contact with
more than one winding for a substantial amount of time. The
high melting point of the nickel coupled with its ohmic resistance
is the key to the heavy-duty operation of the Phenix CTVT.
However, the nickel offers negligible voltage drop across the
regulated voltage circuit between the secondary winding and the
output roller. Therefore, the nickel plating is much better suited
for this application than is silver plating.
Output voltage free is of distortion and harmonics.
The low volts per turn is a design advantage of the CTVT. At 0.7
volts per turn (or less) the output resolution is considerably better
than other regulation devices. A big advantage of the low volts
per turn is that circulating currents are negligible.
Choke coils are incorporated into the CTVT to help maintain
phase balance.
Unique plus-minus design features zero magnetic displacement
which reduces overall mechanical stress
Drive system - The CTVT uses a variable speed motor, screw
and gear drive system to move the roller contacts along the
column surface. This drive system insures that the contacts on
each column are always in synchronization.
If a column should fail you simply take that column out of service
and can still operate at a reduced kVA until repairs are made.
True sine wave output signal.
