Portable High Voltage Surge Generator XHHV515-8L 8uF 25kg Cable Fault Locator DC Withstand Voltage Test Equipment
The XHHV515-8L portable high voltage surge generator combines a DC high-voltage source, an 8 μF energy-storage capacitor and a discharge ball gap in one 25 kg unit, producing adjustable 0-15 kV impulses with up to 900 J energy to flash over high-resistance and leakage cable faults for quick pre-location. Its integrated DC output also performs withstand voltage testing, covering the daily needs of plant and facility electrical maintenance teams.
Built for electrical maintenance teams in industrial plants, mines, petrochemical facilities and field construction projects, where cable faults stop production and every hour counts. The ultra-light XHHV515-8L puts utility-grade flashover locating and DC withstand testing in the hands of plant electricians.

Core Features
Designed for harsh industrial environments from -25 °C to +65 °C, the instrument keeps fault locating and insulation testing available wherever production cables run, without cranes or heavy transport.
Integrates a DC high-voltage source, an 8 μF energy-storage capacitor and a discharge ball gap in one portable unit, replacing the traditional test transformer, control box and pulse capacitor combination.
Dual functions: high-voltage impulse (surge) discharge for cable fault flashover pre-location, and DC withstand voltage testing of electrical equipment.
Complete protection chain: over-current protection (8 mA), over-voltage protection, over-temperature protection (65 °C) and zero-start protection with potentiometer zero output.
Super short-circuit protection: the high-voltage output can be short-circuited directly to ground without damaging the instrument.
High-voltage-side voltage measurement with dual 1.5-class pointer meters for current and voltage; the voltmeter displays the capacitor voltage even in the stop state.
Uniform and controllable high-voltage pulse with adjustable discharge interval, simplifying fault point breakdown and waveform capture.
Designed for 10 kV and below power cable fault detection, complying with DL/T846-2016 and DL/T474-2017.
Traditional Test Transformer Set vs XHHV515-8L
Compared with the traditional test transformer, control box and pulse capacitor combination used in the past, the XHHV515-8L changes field testing fundamentally:
| Comparison Item |

FAQ
Is the XHHV515-8L suitable for in-plant electrical maintenance teams?
Yes. It is designed for fault detection on 10 kV and below power cables inside plants and facilities, complying with DL/T846-2016 and DL/T474-2017. High-resistance and leakage faults that stop production can be broken down by the high-voltage impulse and located quickly without digging trial trenches.
Can it also be used for DC withstand voltage testing?
Yes. Besides impulse flashover discharge for fault pre-location, the built-in DC high-voltage source supports DC withstand voltage testing of electrical equipment, making it a two-in-one instrument for plant maintenance departments.
How portable is it for daily plant field work?
The complete unit weighs no more than 25 kg and measures 540 * 300 * 450 mm. It replaces the traditional combination of a test transformer, control box and pulse capacitor that weighed hundreds of kilograms, so it can be carried to cable pits, trenches and production areas quickly.
Can operators with limited experience use it safely?
Yes. The instrument provides zero-start protection, potentiometer zero output and high-voltage-side voltage measurement with dual 1.5-class pointer meters. Over-current, over-voltage and over-temperature protections are built in, and the high-voltage output can be short-circuited directly to ground without damage, greatly reducing the risk of misoperation.
What are the power and environmental requirements on industrial sites?
It operates on AC 220 V ±10% / 50 Hz ±2 Hz and is rated for -25 °C to +65 °C, covering outdoor cable routes and unheated plant buildings in most climate zones.
