Product Description
The Complete GIS Testing Solution is positioned as a comprehensive platform for customers who need more than a single high-voltage test instrument.
It combines GIS high-voltage withstand testing, partial discharge measurement and insulation diagnostics into a configurable testing solution for GIS manufacturers, utilities, laboratories and commissioning companies.
The concept follows the current direction of GIS testing, where withstand testing and PD measurement are increasingly considered complementary rather than completely independent tests.

Why Choose a Complete GIS Test Solution?
More than a withstand test
The customer receives information about both dielectric withstand capability and PD activity.
More efficient testing workflow
The high-voltage source, measurement system and control system can be designed as one integrated solution.
Flexible for different GIS projects
Voltage level, test capacity, PD measurement method and control architecture can be customized.
Suitable for international projects
The system can be engineered according to the applicable project standards and customer specifications.
FAQ
What standards are commonly associated with GIS high-voltage and PD testing?
Depending on the test being performed, customers may encounter standards such as IEC 62271-203, IEC 60060-1 and IEC 60270. The exact standard and test procedure should be confirmed according to the project specification and GIS application.
What is the difference between IEC 60270 PD measurement and UHF GIS PD detection?
IEC 60270 is associated with conventional apparent-charge measurement using a suitable measuring circuit, while UHF detection uses high-frequency electromagnetic signals generated by PD inside GIS. The two approaches have different measurement principles and application characteristics.
Can one system support both methods?
A customized GIS testing platform can be designed to support multiple PD measurement methods where required.
How do I choose the right GIS test system?
The most important information includes:
- GIS rated voltage
- Required test voltage
- GIS capacitance
- Test frequency
- Required test current
- PD measurement method
- Required PD sensitivity
- GIS configuration
- Indoor or outdoor application
- Factory or field testing
- Applicable standards
Can the system be customized for 110kV, 220kV, 500kV or higher GIS?
Yes. High-voltage GIS testing systems are normally engineered according to the customer's actual GIS parameters rather than selected only by voltage class. For example, commercially available systems cover GIS testing at different voltage levels, while higher-voltage applications require corresponding changes to the test circuit, insulation design, capacity and site configuration.
