AC Test Transformer System

AC test transformer system (Oil insulated type)


SUMMARY


It is especially designed for low capacitive load or inductive load high voltage test,and can supply stable test voltage even if the test load capacitance changing during test, just like pollution test and wet test etc.it can be applied for factory test &type test of power transformer,bushing,surge arrestor,instrument transformer and gis. Product design is conform to the IEC standard.

It's features is as following,

◆ With  module  structure  designing,it  is  very  flexible  to  have  serial  or  parallel connection for meeting kinds of application.

◆ With powerful over voltage protection and high safety design for operation

◆ With digital control system,optical fiber communication,excellent EMC design

◆ With non-pd design and high reliability


MAIN  COMPONENTS


◆ Cylinder or tank type of test transformer

◆ High voltage divider and coupling capacitor

◆ HV filter

◆ Regulating transformer

◆ Compensating reactor

◆ Digital control system
