3695

Programmable Electronic Voltage Burden

The programmable electronic voltage burden, type 3695 is designed for efficient testing of voltage instrument transformers. 

It replaces traditional burdens which are built with passive resistances and inductances. 

The wide range of programmable impedances enables the emulation of most existing national and international standard burdens as well as customer-specific values.
The electronic voltage burden constantly monitors the applied burden accuracy and indicates any burden parameter deviation that may occur 

when testing an instrument transformer for accuracy, thereby connection and handling errors in the complete accuracy test system are minimized. 

* Features

 · The voltage burden type 3695 is suitable for standard voltage ratings. Power levels are selectable over a wide range (up to 75 VA) with cos β = 0.1 to 1 at 50 and 60 Hz

 · High accuracy of 1 % - even with additional external passive burden type 3697 connected

 · The power range can be expanded to 400 VA with an additional passive voltage burden type 3697

 · The load generation principle used in the 3695 unit is electronic, not based on classical passive burdens

 · The internal resistance of the measuring system can be parameterized from the unit user interface and is automatically compensated

 · Remote control possibility via IEEE 488 or RS 232C interfaces

 · Burden values can be retrieved from stored tables based on IEC 61869-3, ANSI C57.13 and VDE 0414 Part 2.

 · Nine individual burden settings (SN, cos β) can be stored and retrieved as needed
