The HZWJF-10kVA/100kV series non-partial-discharge withstand voltage test system is designed for frequency withstand voltage testing, partial discharge measurement, and related scientific research on high voltage circuit breakers, insulators, lightning arresters, switches, mutual inductors, cable accessories, high voltage coils, and other specimens.
The complete set includes an intelligent insulation test comprehensive control system, a digital correction pulse generator, an input unit, a frequency corona-free test transformer, a non-partial-discharge coupling capacitor, a non-partial-discharge protection resistor, an electric regulator, and an isolation filtering device.
Installation requirement: The equipment must be used indoors with a dedicated, high-quality grounding system. Grounding resistance should be less than 0.5Ω — the lower, the better.

Voltage level refers to the test article, not the transformer.
| Voltage Level (Test Article) | Control Section Capacity | Partial Discharge Tester | Boosting Section | Isolation Transformer | Voltage Divider | Protection Resistance |
|---|---|---|---|---|---|---|
| 12kV switches, transformers, switch cabinets, etc. | 5kVA and above | Optional | 50kVA and above | 5kVA | 50kV | 50kV |
| 24kV switches, transformers, switch cabinets, etc. | 10kVA and above | Optional | 100kVA and above | 10kVA | 100kV | 100kV |
| 40.5kV switches, transformers, switch cabinets, etc. | 20kVA and above | Optional | 120kVA and above | 20kVA | 120kV | 120kV |
The main interface of the touch screen performs the same control functions as the upper computer. The panel digitally displays the current test voltage, test current, and other necessary information. It allows manual setup of the boosting curve (rated voltage, local discharge test current, and other necessary parameters) and completes local discharge, withstand voltage, and other tests with a single key.
The panel is equipped with an emergency stop button switch. When pressed in an emergency, the system automatically breaks the main circuit switch. A power button is also provided to start the system with electricity.
The controller has an external control function, providing a start button, stop button, and test result status indicator that can be connected to the generator section. It also has reserved interfaces for external red and green indicators, which can be installed in the main loop body part.
Q1: Is your company a sales agent or a manufacturer?
We are an integrated trade and manufacturing company with our own factory.
Q2: If we need to customize our own brand or have special requirements for the built-in software, can it be customized?
Yes, we accept OEM/ODM/OBM and can customize the built-in software of the product according to the customer's special requirements.
Q3: What is the usual lead time? How long until we receive the order after placing it?
In normal circumstances, products in stock can be received within 5 to 7 days via the fastest international express. Other situations may vary depending on the quantity ordered, whether there are special customization requirements, and the delivery time chosen.
Q4: Considering the large size of the product, how can we ensure it will not be damaged during transportation?
We use professional internal and external packaging to ensure the safety and stability of the products during transportation. For fragile or other special parts, we include an extra set so the customer can use the product immediately upon receipt.
Q5: How do you handle after-sales service? What if there is a quality problem or the customer does not know how to operate the product?
For quality issues not caused by human error, we provide a one-year warranty from the time the product is delivered, plus lifetime technical support. Other after-sales issues are addressed by our professional technical staff within 24 hours. The product comes with a user manual and an operation video.
