High Voltage Surge Generator| XHHV515-8L
The XHHV515-8L high voltage surge generator fully complies with DL/T846-2016 "General Technical Conditions for High-Voltage Test Equipment" and DL/T474-2017 "Implementation Guidelines for Field Insulation Tests". It is mainly used for shock discharge during cable fault testing and can also be used for DC withstand voltage testing of other electrical equipment. Integrating a DC high voltage source, energy storage capacitor and discharge ball gap into one ultra-light portable unit, this device completely replaces traditional hundreds-of-kilograms test transformers, operation boxes and pulse energy storage capacitors, making it an ideal product for power cable fault detection.
Applications & Target Audience: Engineered for electric power cable operation and maintenance teams, power supply utilities, cable manufacturers (factory acceptance testing), third-party electrical testing institutes, and industrial power departments in rail transit, mining and municipal grid projects that need portable high voltage surge generation for cable fault location and DC withstand voltage testing of 10kV and below power cable systems.

FAQ
Q1: What is the maximum impulse voltage and discharge power of the XHHV515-8L?
The impulse voltage ranges from 0 to 15kV and the discharge power reaches 0~900J with a built-in 8μF energy storage capacitor, providing strong pulse energy for cable fault location of 10kV and below power cable systems.
Q2: Which standards does this high voltage surge generator comply with?
It fully complies with DL/T846-2016 "General Technical Conditions for High-Voltage Test Equipment" and DL/T474-2017 "Implementation Guidelines for Field Insulation Tests", ensuring reliable and standardized field testing.
Q3: Can it be used for DC withstand voltage testing?
Yes. Besides impulse discharge for cable fault testing, the instrument also supports DC withstand voltage testing of other electrical equipment, integrating both functions into one portable unit.
Q4: What safety protections are built in?
The instrument features over-current protection (8mA over 4 seconds), over-voltage protection, over-temperature protection (65°C), zero-start protection and super short-circuit protection, allowing the high voltage output to be short-circuited to ground directly without damage.
Q5: How much does the instrument weigh compared with traditional equipment?
The XHHV515-8L weighs no more than 25kg, completely replacing traditional test transformer sets that typically weigh more than 100kg (5kVA transformer over 60kg, control box over 30kg and pulse capacitor over 20kg), making field cable fault testing much easier.
