INTRODUCTION
This Instruction Manual is intended as a guide to the operation
and maintenance of the portable 15 kV Megohmmeter Test
Set, Catalog No. 210415 for use on 120 Volt supply and
Catalog No. 210415-47 used when supply is between 200 and
250 Volts. References in this manual to optional functions and
equipment may be disregarded when such information does
not apply to the Test Set in use. The options included in the
set for which this manual is supplied are indicated in nameplate
data.
The instructions and suggestions provided in this manual
anticipate the normal use of the Megohmmeter Test Set for
testing electrical insulation systems on such equipment as
motors, generators, bushings, and cables. These tests, which
are based on measurement of the applied dc voltage, the
equivalent resistance, and the manner in which resistance varies
with time, provide data that indicate the condition of the
insulation system of the apparatus being tested. When these
data are recorded on graph paper such as Megger Ki1ovo1t-
Megohm Paper (Catalog No. 220000), the shape of the curve
made by connecting the plotted points will aid in evaluating the
condition of the insulation system. Information on the
interpretation of observed data and guides for testing are given
in Section 10.
