THIẾT BỊ KIỂM TRA PHÓNG ĐIỆN CỤC BỘ SEBA PD LOC
MODEL: SEBA PD LOC
HÃNG SX: SEBA - ĐỨC
DESCRIPTION
The PD Loc is used to precisely locate any identified PD weak spots during an offline PD diagnosis. In most cases, exact joint positions or cable parts are unknown; with help from the PD LOC this problem can be solved and joints or cable parts can be replaced, as part of preventative maintenance programm. This independent of the cable type: it functions on pure PE/XLPE, PILC, EPR as well as on mixed cable types. The system consists of the PD TX impulse transmitter and the Teleflex SX receiving/evaluating unit (can also be ordered without Teleflex SX). The Teleflex SX unit consists of an input amplifier for processing the signal and a control unit in a rugged case. The visualisation, which shows the distance of the transmitting unit of the system, is shown on the reflectometer. The pulse transmitter PD-TX can control the pulse width and displays the battery and charging status. The impulse transmitter continuously transmits a sufficiently strong impulse signal into the exposed cable via an inductive coupler (42 or 64 mm) or test lead.
■ Precise PD pinpointing in mixed cable networks as well
■ Easy to connect
■ Battery operated transmitter DESCRIPTION These impulses and their reflections from the far end of the cable are recorded and visualized by the Teleflex SX working in a particular operation mode. The time difference from the incoming reflection is used to calculate the distance to the injection point of the impulse which in turn is compared with the results of the previously recorded PD measurement. In many cases, this approach facilitates highly precise positioning of the fault location, helping to avoid unnecessary and cost-intensive excavation when replacing or repairing a cable. When using the system on cables with a lead, aluminium or dense copper wire sheath, please be aware that the quality of the shielding may limit these devices’ functionality.
