The phase sequence can be detected by no need peeling off the wire and without touching the bare high-voltage fire wire, just directly clamping three super-inductive high-insulation clamps on the insulation skin of the three-phase fire wire respectively. At the same time, acousto-optic indication of the positive or reverse phase state of the phase sequence of the three-phase power supply... -
China High Quality battery tester price Manufacturer – GDKH-10 Battery Activator – HV Hipot
General Information In all operating equipment and operating network systems with increasing informationization and automation, uninterrupted power supply is the most basic guarantee. Whether it is AC or DC uninterruptible power supply system, the battery acts as backup power source plays an important role in power source system. Usually, the battery is in the state of floating charge standby. Once the AC power is lost or other accidents, the battery becomes the sole energy supplier of the load. We know that in addition to the normal life cycle of the battery, some of the early failure of the battery may occur due to problems such as the quality of the battery itself, defects in materials, structures, processes, and improper use. In order to verify the standby time and actual capaci... -
OEM Best electrical earth tester Manufacturers – Online Monitoring System of Circulating Current on Cable Sheath GDCO-301 – HV Hipot
General Information Cables above 35kV are mainly single-core cables with metal sheath. Since the metal sheath of the single-core cable is hinged with the magnetic field line generated by the AC current in the core wire, the two ends of the single-core cable have a high induced voltage. Therefore, appropriate grounding measures should be taken to keep the induced voltage within the safe voltage range (usually no more than 50V, but no more than 100V with safety measures). Usually, the metal sheath of short line single-core cable is grounded directly at one end and grounded through gap or protection resistor at the other end. The metal sheath of long line single – core cable is grounded by three – phase segmental cross – connection. No matter which kind of grounding me... -
