4.- PREPARATIONS BEFORE TO USE
The UM2B equipment is an automatic, high performance system especially
designed for the assessment of transformer recovery voltage parameter. For
performance of the measurement, the system provides high voltages (up to
2000 Volts d.c.) during testing, this possibly implying serious danger for the
equipment operator if the system is handled incorrectly.
Consequently, IT IS CONSIDERED ESSENTIAL THAT THE
OPERATOR IN CHARGE OF HANDLING AND MAINTAINING
THE EQUIPMENT RECEIVE TECHNICAL TRAINING
.
Likewise, all persons performing or witnessing a test should take the necessary safety
precautions, in order to avoid any contact with the parts to be analyzed or forming part of the
measurement system, remaining at some distance from them unless these parts are free from
voltage and grounded.
Measurements performed using the UM2B system are carried out
OFF-LINE. Consequently, prior to beginning the test, THE SYSTEM
SHOULD BE VERIFIED TO BE FREE FROM VOLTAGE/LOAD.
If the equipment is damaged during the warranty period as a result of
inappropriate use, without following the instructions described in this
chapter, the repair may be excluded from the warranty.
