Product Description
The Custom GIS High Voltage Testing System is a project-based solution for customers who need a complete GIS insulation testing system.
Instead of using a standard product configuration, the equipment can be engineered according to:
- GIS rated voltage
- Required AC test voltage
- GIS capacitance
- Test duration
- Frequency range
- PD measurement requirement
- Factory or site application
- Laboratory dimensions
- Available power supply
- Applicable standards

What Customers Usually Want to Know
1. Can you design the system according to our GIS?
Yes. The technical proposal should be based on the actual GIS electrical parameters.
2. Can you provide a complete solution rather than individual equipment?
Yes. The solution can include the AC resonant system, PD measurement, voltage divider, control system, safety protection and related accessories.
3. Can you provide technical documents?
A project package can include technical specifications, system configuration, drawings, operation manuals, test procedures and relevant documentation according to the contract.
4. Can you support FAT and commissioning?
Factory acceptance testing and installation/commissioning support can be included according to the project scope.
