DL-1020 High voltage Kilovoltmeter (45Hz~55Hz，，，，，0~65kV)
DL-1020 Kilovoltmeter is designed for measuring voltage or conduct voltage tests (inductance tester) for both low- voltage or high voltage cables in environments where it is hard to reach. The instrument makes measurement by detecting the electric field. For cables below 65kV, using the contact method of the instrument, regardless if it is a neutral wire, live wire, ground wire, high-voltage transmission line, a metal conductor, or just some current leakage caused by some insulation damage, as long as there is an electric field, this instrument can detect the signal. Once the transmitter detects the electromagnetic field, it will emit a "beep-beep-beep-" buzzer sound. For cables above 65kV, although it cannot be used to measure the voltage, it can be used as an inductance tester to detect live wires and voltage.

Induction Intensity | During high-voltage tests, based on the strength of the induced electric field, the transmitter will automatically adjust the 2KV, 20kV, and 65kV range, which is suitable for densely packed environments. The 2KV range is the default when the instrument is turned one, and the induction is the strongest |

Dimension | Transmitter：LWD275mm×105mm×52mm Receiver：LWD250mm×100mm×45mm |
Line voltage | Bare wires below 65kV can be directly contacted for testing; bare wires above 65kV must be tested with the non-contact method; it can also be directly hung on lines with intact insulation over 110kV for testing |
Contact method | When conducting the electrical test: the collector is connected to the metal probe hook or probe, and the metal probe hook or probe needs to be in contact with the bare wire to ensure the accuracy of the electrical test and voltage test |
Sound Feedback | When the induction voltage or detected voltage is higher than 20V, the internal buzzer of the transmitter will emit a "beep --beep -- beep --" sound with lighting to warn the user |
