Product Overview
The Portable Variable Frequency Series Resonant Test Equipment is designed for high-voltage testing projects that require transportation between laboratories, substations, cable installation sites, and maintenance locations.
A modular configuration can divide the test system into manageable components, including the variable-frequency power supply, excitation transformer, high-voltage reactor sections, voltage divider, and control equipment.
The series resonant method allows the system to generate the specified AC test voltage while reducing the input power required to compensate for reactive power, subject to the actual test conditions.
Portability depends on the system rating, number and dimensions of reactor sections, transportation requirements, and site configuration. A suitable design must balance output capacity with the practical needs of field deployment.

Key Buyer Pain Points
Transportation challenges: We can discuss component dimensions, weights, lifting arrangements, and transport packaging according to the proposed system.
Limited site power: The required input supply can be evaluated based on the test voltage, load capacitance, operating frequency, and system losses.
Difficult site conditions: The proposed arrangement can consider available installation space, access routes, environmental conditions, and grounding provisions.
Frequent changes of test objects: Modular reactor combinations may support different test conditions, provided the required electrical limits are met.
Frequently Asked Questions
Q1: Is every series resonant test system portable?
No. Portability depends on the rated voltage, capacity, reactor design, dimensions, and project requirements.
Q2: Can the system be used for outdoor testing?
Suitable configurations can be designed for field use. Environmental limits and site safety requirements must be confirmed.
Q3: How many people are needed to install the equipment?
This depends on the system dimensions, lifting requirements, component weights, and site arrangements. Installation requirements should be defined in the project documentation.
Q4: Can the system operate with a limited power supply?
The series resonant principle can reduce required input power, but the actual supply requirements must be calculated for the intended test.
Q5: Can the system be customized for a service company?
Yes. The equipment configuration can be developed around the company's typical test objects, transport arrangements, and operating conditions.
Q6: What information should we provide?
Share your intended applications, required voltage, test-object capacitance, transportation constraints, site power supply, and destination country.
