SYWZJ-B portable DC grounding detector Introduction: At present, the core problem of power system DC power supply ground fault finding is that the field interference is large, and it is measured under different DC power sources and different working conditions. Most products will be misjudged and misjudged, and the anti-interference is poor. Our products are rapidly developed. Based on this market, it is because the interference problem has been successfully solved. SYWZJ-B portable DC system ground fault locator is developed and produced by sinusoidal signal phase advance processing technology and data transfer algorithm technology (latest patented technology). This product is between the fixed and mobile types. It is mobile and the performance is online. When searching for DC system ground fault, it does not need to disconnect the power supply to achieve grounding point positioning. The instrument can not only detect the resistance of the DC system grounding resistance, but also detect the capacity of the DC system grounding capacitor, and provide a reliable and accurate instrument for the detection and location of the grounding fault of the power DC system. Features: 1, 24V, 48V, 110V, 220V DC system share a set of DC grounding detectors. 2. The DC system ground fault can be completely eliminated, and the large-capacitance interference is distributed on the site, and the fault is locked to the minimum range accurately. 3. Measurement accuracy: 100%. 4, signal output power: <0.15W, built-in current limiting protection, no impact on relay protection, automatic, operating loop, safe to use. 5. Signal frequency stability: ±0.02HZ. 6, using the "heart" design of the jaws, large and small lines are shared, no need to change the pliers. 7, can adapt to the grounding caused by AC and DC series, the ring network power supply grounding, diode isolation power supply grounding, high resistance grounding. 8, no installation, no power outage, without shaking insulation, you can quickly and accurately find one or more points of grounding. 9, luxury aluminum alloy packaging, easy to carry. Technical Parameters: Adapt to ambient temperature: -10 °C + 50 °C Locator working voltage: 12V (lithium battery work) Output signal voltage and frequency: voltage: 5VP-P; frequency: 2.5Hz Grounding resistance detection range: 0-60 KΩ Grounding resistance measurement accuracy: error ≤ 10% Power consumption: less than 10W Dimensions (length × height × depth): 125 × 90 × 125 (mm) Weight: 3.5kg
