Product Description

XHHG521B

Product Description

XZH TEST XHHG521B is designed for cable sheath fault locating, high-voltage bridge cable fault tester is designed based on the principle of MURRAY bridge. It can be used to locate the breakdown points of various wire and cable after laying and the defect points with no breakdown but low insulation resistance. Of course, it can also be used to locate the defective points of various cables in the cable factory.

Function

The high-resistance breakdown point of the cable after laying, especially the linear high-impedance breakdown point that is difficult to fire into low resistance, such as the linear high-resistance breakdown of the middle connector of the cable.
Flashover type breakdown point, after the breakdown, the constant current source can maintain the arc, there is a stable current through the bridge, the bridge has sufficient sensitivity.
Has not broken down, but the defect point of low resistance, such as the use of megohmmeter found low cable resistance, but the operating voltage does not break down the insulation defect point.

Precautions for Use and Common Faults
1. Do not touch the high-voltage connecting cables or the cable under test during testing to avoid high-voltage injury.
2. Do not power on the instrument while connecting cables; turn off the power immediately after the test is completed.
3. The instrument cannot be started unless the voltage adjustment control is at the zero position.
4. Operation requires the presence of at least two people: one to handle connections and the other to verify them; the test may only begin after everything has been confirmed correct.
5. The instrument's grounding terminal must be reliably grounded using a dedicated grounding cable; preferably, connect it to points such as a test site grounding post, an electrical cabinet grounding busbar, or the base of a piece of machinery.
6. During the test and after its completion—and before anyone touches high-voltage components—the system must be discharged, and the grounding wire must be attached.
7. Automatic fault distance calculation must be performed while the voltage is not raised (i.e., before applying high voltage).

Bhai, this pulse generator is total game changer for our discom team. Six months heavy use across Uttar Pradesh — heat, dust, monsoon humidity, still going strong. Fault detection is spot on, saves us hours of digging every time. Build is tough, no-nonsense. And the price? Forget those fancy foreign brands charging 3x more. This is proper value for money. Our linemen love it. Must buy for any electricity department. Jai power!

Полгода в поле с ним таскаюсь — не подводил ни разу. Глубину бьёт точно, частот на все случаи жизни, батарея держит до вечера даже в мороз. Крепкий, как танк, пыль грязь — нипочём. За эти деньги — огонь! Сетевым и подрядчикам советую, не пожалеете.
