GDHX-9500B Phase Detector
•Using wireless transmission technology, its basic working principle is real-time phase comparison.
•Please observe and follow the regulation to use this product, in order to ensure the safe operation of the instrument, the ends of X and Y detector are not allowed to make withstand voltage test.
•The metal head parts of the insulating rod is strictly prohibited to contact with any objects during the test.
•Please comply with the national power industry safety regulations of preventive test for safety tools and products.
•Please pay attention to the training and examination for staffs who work on high-voltage live lines or near the high-voltage lines.
•Phase calibration on live equipment must be carried out by insulating rod.
•Test voltage: 10V-500kV, suitable for different voltage level.
•Accuracy: self-calibrating error ≤±3°.
•Sampling speed: 10 times/s.
•Screen contrast: adjustable display clarity.
•Back-light time setting: normally on, normally off, 0-60s can be set by user.
•Auto power off setting: never or 0-10mins can be set by user.
• In-phase: ≤30° is considered as in-phase (phase threshold within 0-60°, can be set by user. The system default is 30°.)
•Out-phase qualitative: >30° (phase threshold within 0-60°, can be set by user. The system default is 30°.)
• Field calibration function: on-site calibration for measured lead, ensure the accuracy of phase angle.
• Transmission distance between handset and X, Y detector: X≤200m, Y≤200m.
• Multiple mode design, with strong applicability, more safe and convenient.
• Unique human-computer interaction interface, simple operation.
•FCC antenna design, the signal is stronger and easier to penetrate the blocking of wall, door or barrier.
•Double shielding, strong an-ti interference, in full accordance with EMC standards.
• Charts and data display, more convenient and easy to read.
• Qualitative measurement, display by sound and light signal.
•Quantitative measurement, real-time display phase angle difference, error≤5°.
•Phase sequence calibration, positive phase sequence, negative phase sequence (120°, 240°).
