The power frequency withstand voltage test equipment uses series resonance withstand voltage test equipment for voltage withstand testing. It is the newest generation, particularly suitable for AC withstand voltage testing of large-capacity capacitive test objects. It is very convenient for on-site use. During operation, the insulation of power equipment is gradually degraded under the long-term effects of electric field, temperature, and mechanical vibration, including overall degradation and partial degradation, forming defects. The power frequency withstand voltage test equipment is the most effective and direct method to identify the insulation strength of power equipment and is an important part of preventive tests. In addition, since the AC withstand voltage test voltage is generally higher than the operating voltage, the equipment has a large safety margin after passing the test. Therefore, the AC withstand voltage test is an important means to ensure the safe operation of power equipment.

　　Precautions for Power Frequency Withstand Voltage Test Equipment

　　1. Most resonant power supply products are high-voltage test equipment and are required to be used by professional high-voltage test personnel. Before use, read the instruction manual carefully and undergo repeated operation training.

　　2. The number of operators should not be less than 2. During use, strictly abide by the safety operation regulations for high-voltage tests of the unit.

　　3. To ensure the safety and correctness of the test, in addition to being familiar with this product manual, it is necessary to strictly follow the relevant national standards and regulations for test operation.

　　4. The connection lines must not be connected incorrectly, especially the grounding wire. Otherwise, it may cause damage to the test equipment.

　　5. When this device is in use, it outputs high voltage or ultra-high voltage. It must be reliably grounded, and pay attention to the safe operating distance.

　　Performance Characteristics of Power Frequency Withstand Voltage Test Equipment

　　1. Intuitive reading: This instrument uses a digital LCD meter to directly display the test values of high voltage, instrument voltage, low-voltage current, and high-voltage current, which is convenient for observation and recording during the test.

　　2. Accurate measurement: Fully digital processing, built-in precise mathematical model, high measurement accuracy, and accurate test values.

　　3. Accurate protection function: Fully digital processing, the setting of overcurrent protection value, timing voltage, and overvoltage protection value are all implemented digitally, making protection more accurate.

　　4. Automatic timing: The power frequency withstand voltage test equipment has a timing trigger function. The equipment automatically times according to the set voltage value, making timing more accurate and effective.

　　5. Easy to carry: Small size and light weight, the volume is only 30% to 70% of similar products, making it very convenient to carry.
