During the testing, various test sheets are completed and copies are issued to our customers. Examples of the testing undertaken during commissioning includes:
- Insulation Resistance Tests
- DC Pressure Testing
- VLF Testing
Cable Fault Location
We can attend site to investigate suspected cable faults. Fault finding on switchgear will be carried out to eliminate any faults before progressing to testing of the cable.
Our cable fault services include, but are not limited to:
- Issue of permits required to work/fault find
- Identification of cable
- Location of fault within the cable
- Jointing of cable to facilitate repair
- Test and commissioning of the cable back into service
