Fully automated heat and electrical testing of transformers complying to the EN 61558-1 standard

The transformer testing device enables the fully automated testing of transformers complying to the EN 61558-1 standard.
The complete device is a simple 19" rack design comprising all the necessary components.
The electrical connecting panel for the test samples is located in the upper part of the device. Transformers with one primary and up to 3 secondary windings can be connected.
The device also has 16 thermocouple inputs located in its upper part for connecting temperature probes (to standardize testing sample temperature and room temperature).
The electronic load is located below the connection panel. This permits the test samples to be exposed to a constant current and/or resistance.

Measuring equipment is located in the lower part of the device for accurate measurement of the electric values voltage,current and power (primary and secondary), for currents from a low mA and up to 200A.

A normal PC with networking capability is used for operation functions. A Windows based PC-Software software is included in delivery.

Easy installation - testing can begin immediately.

Features

  • Test samples from < 1 VA up to 1.5 kVA, 50/60Hz
  • 1 primary winding, up to 3 secondary windings
  • Automatic testing procedure for the required test stages
  • No requirement for costly manual measurements
  • Independent thermal persistence test
  • Testing of R-cold, R-warm and winding temperature
  • Testing of current / voltage / power
  • Normal warming test stage
  • Test under no-load / short circuit / overload conditions
  • Output of standard test report

Testing procedure

The user friendly software for the transformer testing device runs on standard PCs under Windows operating systems. It enables the input of all relevant test parameters. The overall testing procedure can be broken down into test stages which run automatically.
Each test stage can be halted at any time. At the end of the testing procedure a test report can be produced.
The following test stages show that the testing procedure complies to EN 61558-1:

  • Input of parameter for the test sample and test conditions
  • Testing under normal operation, 1.06 % of nominal voltage
  • Testing under overload at 1.06 % of nominal voltage
  • Short circuit test
  • Test reports

Prüfungsablauf

Die einfach zu bedienende Software für das TPG läuft unter einem Windows Betriebssystem auf Standard-PC. Sie ermöglicht die Eingabe aller relevanten Prüfparameter. Der Prüfungsablauf kann in wesentliche Prüfungsschritte aufgegliedert werden und läuft automatisch ab.
Die jeweiligen Prüfungsabschnitte können jederzeit unterbrochen werden. Nach dem Ende des Prüfungsablaufs kann ein Prüfprotokoll ausgegeben werden. Folgende wesentliche Prüfschritte kennzeichnen einen Prüfungsablauf des TPG nach EN 61558-1:
 
 

  • Eingabe der Parameter für Trafotyp und Prüfbedingungen
     
  • Prüfung Normalbetrieb bei 1,06facher Nennspannung und Last
  • Prüfung Überlast bei 1,06facher Nennspannung
  • Kurzschluss-Prüfung
  • Protokollierung bzw. Ausgabe der Prüfergebnisse
