Portable 32kV 1024J DC Impulse Surge Generator 2uF for Underground Cable Fault Location and Testing|XHHV535-2L

The XHHV535-2L is a practical portable DC high-voltage impulse surge generator delivering 1024J discharge energy at up to 32kV for underground power cable fault location and DC withstand voltage testing. Engineered for everyday field reliability, it combines essential impulse testing capabilities with a straightforward, no-frills design that keeps both acquisition and maintenance costs low.

The unit integrates a DC high-voltage source, 2μF energy storage capacitor, discharge ball gap, and automatic discharge device into a compact, accessible form factor. Its standout practical feature is the dual EMP and DC output terminals—eliminating cable swaps when switching between impulse fault location and DC withstand testing. A built-in time relay with adjustable 0–100s discharge intervals enables hands-free cyclic operation during extended fault search operations. The front panel includes a manual ball-gap discharge button, zero-start protection with potentiometer return-to-zero, emergency stop, and comprehensive over-current (8mA/3s), over-voltage, and over-temperature (65°C) automatic protection.

The XHHV535-2L is built for entry-level cable testing teams, municipal utility workshops, vocational training centers, and cost-conscious contractors in developing markets—organizations that need reliable 32kV impulse fault location and DC withstand testing at an accessible price point. Its EMP/DC dual terminal design and 0–100s adjustable timer make it especially suitable for training environments where students need to learn both fault location and withstand voltage procedures on a single instrument, and for routine maintenance programs where daily reliability matters more than high-end precision. For premium performance with 1.5-level accuracy and higher discharge energy, see the XHHV535-4Z (35kg, 2450J) or XHHV535-2L upgrade (25kg, 1225J).
