Megger Easytest 20 kV - Functional Description

2-11
2.3 Functional Description
Operation modes The Easytest system offers the following operation modes:
• DC testing (Hipot) up to 20 kV negative output voltage for testing the dielectric
strength of new or disconnected cables (particularly
for paper insulated lead
cables (PILC))
• AC testing up to 20 kV AC voltage for testing the dielectric strength of new or
disconnected cables.
• Sheath fault testing: up to 5 kV / 10 kV
• Sheath fault pinpointing: up to 10 kV; duty cycling 1:3
Features The Easytest combines the following features in a single device:
• Test parameters like test duration and test voltage can be specifically specified for
each operation mode. Setting the test duration to 0 minutes causes a permanent
test which can be interrupted by the HV off button (7).
• The test voltage can be adjusted using the navigation buttons even if the test is
already running.
• Leakage current measurement
• Automatic current range switch
• Automatische Strombereichsumschaltung
• Constantly updated bargraph indicating the progress of the running test
Options
Depending on the present system configuration, the Easytest
offers the following
additional functions:
• Logging function to analyze / archive test data using Excel or WinkisVLF
• External voltage protection
• Trolly for easier transport of the Easytest unit
