APPLICATIONS
|
|
All
three models are designed for testing the insulation of high-voltage electric
equipment.
|
|
Their
wide voltage range also allows applications for low-voltage equipment. Generators,
|
|
motors, transformers, cables and switchgear
all require effective maintenance. The test
|
|
techniques on the instruments provide valuable
diagnostic information.
|
|
|
|
All
three instruments test the insulation resistance of:
|
|
High-voltage power cables and
high-voltage buses
|
|
Large motor/generator windings
|
|
Line and substation transformers
