The internal coupling network is designed for mains frequency 50 Hz / 60 Hz.
When L – N coupling is selected an additional current of approx. 1.5 A flows, caused by the
18 F coupling capacitor and the pulse forming network. A similar current appears during the
couplings to PE.
Tests with 400 Hz mains frequency destroy the coupling network. An external coupling
network is recommended with inductors and capacitors matched to the 400 Hz mains
frequency.
The Surge menu offers different test routines for surge testing.
Quick Start
Easy and fast online-operation with the phenomenon Telecom Surge. In this menu the user can operate all surge
test manually with online change the most parameters during a test.
Standard
The operator can select between various preprogrammed test routines as required in different standards
The standard library includes IEC, ITU and ETSI standards
Extended Tests
The operator can select between various preprogrammed test routines which helps to accelerate testing and
which are very helpful especially during design.
User test routines
The user defined library where all created Surge tests are stored.
Easy Link
Link files library created during the actual session. The user can easy save a test into the Easy Link library. After
switch off the Equipment all Easy Link tests are deleted. Use “SAVE AS USER TEST” for definitive save the test.
