Description



The 3691 is a universal high accurate current burden for standard current ratings with freely adjustable power steps up to 75 VA. With the additional burden extension type 3692 the power range is expandable up to 200VA.This programmable current burden unit is ideal for integration with the 2767 or 2763 test set in a full remote controlled instrument current transformer test system.

1% accuracy (even with additional passive burden).
Burden values can be retrieved from the stored IEC60044 and ANSI C57.13 standard tables
Internal test set resistance, input cable and contact resistances are compensated by four-conductor measurement. This electronic current burden can be used too with different current transformer test set, i.e. Tettex types 2711/22, 2761 or from other suppliers.
Storage of nine individual burden settings (SN, IN, cos β), which can be retrieved as required
The power range can be extended to 200 VA with additional passive burdens
Universal current burden for standard current ratings, freely adjustable power steps up to 75 VA, cos β = 0.5 to 1 at 50 and 60 Hz.

Simple use by interactive parameter entry.;The burden can be fully integrated in an automatic measurement process via an optional interface.;A cost-effective solution, since a single electronic burden can replace most conventional passive burdens.
