Transformer Test Equipment

All primary components in a complete system are developed

and tested in the ZERA plant. This includes particularly.
automatic tests of current transformers.
 •  Construction of equipment and switch cabinets as well
   as production of key technologies
 •  Constant current power supplies based on electronic output
    amplifiers in the range for 10VA to 80 KVA and
•   High precision test equipment for measuring electrical values
    and development of programs fro
•  Programmable Logic Controls ( PLCs )
 •  Real time applications
 •  Controllling data processing State-the-art engineering is used
   mation
 •  lmage processing systems for precise path measurement
   without caontact
 •  Multiple axis robots for assembly and feed in addition to testing
   technology, ZERA also integrates assembly engineering appli-
   cations:
 •  Part marking:
•  Tampon printing
•  Automatic labeling
•  Laser printing
•  lnkiet  printing
•  Part recognition
 •  Bar code scanners
 •  OCR systems

Measuring Bridge for Testing of current Transformer WM303-I

General

• The new designed measuring bridge WM 303-I can be used in

   transformer test laboratories for manual semiautomatic and
   automatic tests of current transformers.
Features
•  The consequent use of the newest generation of 20-bit
    dual-AD-converters is guaranteeing a high precise
    measurement of the N- and X-current.
•   With this measurement principle the ratio error and the 
    phase displacement will be measured with very high accuracy
•  The WM 303 - I can operate in two measuring modes:
-   In the ABSOLUTE mode, the WM 303 - I will
-   measure the absolute currents of the standard transformer
    under Therefore an adjustment of the secondary current is
    possible by using an internal programmable divider. lnthis mode
    the WM 303 - l is operating self - calibrated
-   ln DIFFERENCE mode the WM 303 - l will measure the current
    of the standard transformer and the differential current
-   The WM 303 - l is controlled by an external PC with Windows-
    based control software.

Measuring Bridge for Testing of Voltage Transformer WM303-U

General
 •  The new designed measuring bridge WM 303 - U can be used
    in transformer test laboratories for manual semiautomatic
    and automatic tests of voltage transformers
Features
 •  The consequent use of the newest generation of 20-bit-dual

    AD-converters guaranteeing high precise measurement of the
    N - and X-current.
 •   With this measurement principle th ratio error and the phase
    displacement will be measured with high accuracy.
 •   The WM 303 - U will measure the absolute voltage values
    of the standard transformer and the transformer under test
    Therefore an adjustment of the secondary voltage is possible
     by using an internal programmable divider is possible
 •   The WM303 - U is controlled by an external PC with Windows
     based control software

   Electronic Compensated Standard Current Burden ESCB 200

General
•  The new developed and programmable electronic current
    burden ESCB can be used in transformer test laboratories
    for manual, semiautomatic and automatic tests of current
    transformers.
 •   The ESCB is characterised particularly by the user-friendly
     menu guidance by means of inserted functionkeys as well as

     the 10,4 TFT - mono chrome display.
 Features
 •   For the ESCB is no external burden adjustment required
 •   The menu - quided control the ESCB is possible either by   
     using the built-in soft - key terminal
 •   The ESCB can be calibrated in the array of their
    specifications for everytransformer.
