Description
Changers where it delivers test currents for the measurements.
The load tap changer is the only moving part connected to the
transformer windings. Taking a transformer off the system to
investigate an internal problem with a tap changer is an expensive
exercise; therefore it is in every utility’s interest to carry out condition
assessments of their tap changers to help detect developing faults at
an early stage.

LTC135 is designed to be used together with the following Megger
instruments:
EGIL
TM1600/MA61
TM1700 series
TM1800
Together with the circuit-breaker analyzer (CBA) it becomes a a test
setup for performing dynamic measurements on load tap-changers.
The unit can also be used for winding resistance measurements
and other applications where a constant DC current test signal is
requested. It is a power supply designed for DC current testing
of inductive loads with provisions for discharging the transformer
winding when the test is finalized.
