Product Description
680kVA 270kV Variable Frequency AC Resonant Test System
This 680kVA 270kV Variable Frequency AC Resonant Test System is intended for specified high-voltage AC withstand voltage testing applications involving compatible capacitive electrical equipment. The 270kV rated voltage and 680kVA rated capacity provide key reference values for customers planning high-voltage testing facilities, substation commissioning projects, and electrical equipment acceptance tests.
Gas-insulated switchgear (GIS) are important application categories for consideration in 110kV and 220kV substation projects. The actual test arrangement depends on the equipment design, electrical characteristics, required withstand voltage, capacitance, test duration, site conditions, and applicable specification. Sansion Power can review the customer's technical requirements and discuss a suitable system configuration. The final proposal should identify the agreed resonant reactor arrangement, variable-frequency power supply, excitation transformer, voltage measurement, control functions, accessories, and any additional diagnostic equipment required by the project. Partial discharge measurement should be confirmed separately if it is part of the required scope.

FAQ
Q1: Can this system be evaluated for GIS testing in 110kV and 220kV substations?
A1: Yes, these are relevant application scenarios. The required test voltage, equipment characteristics, and system configuration must be verified for each project.
Q2: Is PASS equipment included in the application scope?
A2: PASS is a relevant application category for technical evaluation, subject to confirmation of the equipment specifications and test requirements.
Q3: Does the system include partial discharge measurement as standard?
A3: The supplied information does not confirm this as a standard function. Any required PD measurement or diagnostic equipment should be specified separately in the technical proposal.
Q4: What details should be supplied for a GIS project quotation?
A4: Provide the GIS type, rated voltage, required test voltage, capacitance if available, test duration, applicable specification, site conditions, and requested scope of supply.
