Performed in two steps:<\/p>\n\n
Test level on request; otherwise, levels of 2 kV, 5 kV or 10 kV are used depending on sheath type. A measurement protocol is established.<\/p>\n
Performed in two steps:<\/p>\n\n
We can measure PD (Partial Discharge) using two different methods:<\/p>\n\n
We perform testing with VLF (Very Low Frequency) \u2013 CR (cosine rectangular voltage) at 0.1 Hz. The test reveals most potential faults or weaknesses. It is a rigorous test. Only a few cables that pass it suffer cable faults after commissioning.<\/p>\n\n
Voltage Testing\u2028We can perform testing with two different types of voltage:
<\/strong><\/p>\n\n
Test level upon request; otherwise, use 1 kV for cables under 1 kV, and 5 kV for cables over 1 kV. A test report is prepared.<\/p>\n
We can perform cable laying\/location marking in:<\/p>\n\n
Identify one specific cable among many in a trench, so work is safe and no incidents or accidents occur. The cable is marked according to the customer’s requirements.<\/p>\n
We can perform control of shield and external return circuit of earth leakage current (\u201cYmer testing\u201d). Usually conducted together with insulation\/sheath testing and documented in a report. Should be done before commissioning a new cable or when splicing an existing cable.<\/p>\n
We can perform groundelectrode measurements on new or existing ground electrodes but need different information depending on whether the electrode is:<\/p>\n\n
<\/strong>For new installations of ground electrodes we can assist with measuring soil resistivity so that the installation can be optimized:<\/p>\n\n
