Demo Cable Locators inside the office with a direct connection is not available (use Clamp) (Finding the exact location of the cable fault inside the office and outside is the same)
Cable Damage Detection, Before Using Cable Locators, we will use – Demonstrations of cable locators inside the office. In order to determine the exact location of one of the three faults. We will use three core cables (without voltage), 3 and 15 meters long, connected as follows:
|1. If phase short circuit – Finding the exact location of the cable fault|
|2. If phase short circuit to ground – Finding the exact location of the cable fault|
|3. If Phase break – Finding the exact location of the cable fault|
Cable Damage Detection – Electromagnetic location methods series “Success ATG”, “Success AG”, “Athlete” company “TECHNO-AC” (Kolomna). The main disadvantage of the electromagnetic location method is that with its help can not be held tracing plastic pipes. Solve this complex problem, apply only acoustic location method based on listening from the ground. With an acoustic sensor the signal generated by the sound pulse generator pipeline.
Electromagnetic location methods thus, to solve the whole complex of tasks on localization of underground communications in the kit should include a generator of sound pulses. Currently, the only domestic device such type developed and produced LLC “TECHNO-AC” (Kolomna). Foreign analogue of the RSP-3. The presence of an acoustic sensor for a series of devices “The success of the ATG”. “The success of the TPT” in addition to tracing pipelines from any materials.
Electromagnetic location methods, allows you to solve the problem of finding places depressurization of pipelines and places of damage cable-induction and acoustic lines. In addition, the presence in the set of sensors step voltage (DKI, DODK). Allows you to search for a place of decrease insulation resistances of the external covers of communications. And Also search for the place of cable damage by the capacitive method. To solve the problems facing the services, operating underground communications.
