5250 Basic Mode | "How-To" Video

The 5250 series is available with voltages up to 15kV DC or 30kV DC and up to 2000J. The 5250 series is designed to allow the user to quickly and efficiently locate underground cable faults. Let's start by powering on the 5250. First let's switch on the power of the capacitive discharge portion, and next we'll make sure that the unit is in TDR Mode. Then we'll open up the TDR case and then power on the TDR. For this demonstration, let's operate the unit in Basic Mode and walk through the cable fault locating test sequence. Let's assume this is the first time operating the 5250. Fist we must set up the unit's hook up point. The hook up point takes into consideration the additional cable from the unit, or a cable reel as well. To set up the hook up point let's go into advanced mode. Your unit may or may not be password protected if it is please enter the password, and then hit "ok". In Advanced Mode, press the "Adjust" option and the TDR will display six options including "Hook-up Point". Press "Hook-up Point" and now we are ready to set up the hook up point. Next the TDR will prompt the operator to short the connecting cable leads together. At this point you will want to put on your rubber gloves. Pick up the high voltage return lead and the high voltage lead as well. You want to clap the two together. Then hit "ok" on the TDR. Next, the user will be prompted to open the circuit like so. You can throw the leads on the ground. Take your gloves off and then press "ok" on the TDR. The TDR will display a green line over the red line prompting the user that the hook-up point has been found. The intersection point where the red line begins to depicts the "short" as a negative inflection, and the green line begins to depict the "open" as a positive inflection, is where the "Start Cursor" will automatically be placed. Pressing the "Cursors" option will allow the "Start Cursor" position to be adjusted using the red, rotary knob if the automatic placement does not seem accurate. Once satisfied, press "OK" and the Hook-up point will be saved and the TDR will revert back to the "Adjust" menu. Once saved the hook-up point will not have to set up again unless the "Start Cursor" is adjusted by the user during the fault locating sequence. Now, press "Main Menu" and then press "Basic Mode" to get back to the Basic Mode main menu. Now we are prepared to make our connections to the faulted cable. First, ensure the faulted cable is properly de-energized and disconnected from the load-break or elbow. Next connect the ground leads from the 5250 to the system ground. This may be a grounding rod or a vehicle. Next connect the high voltage leads. A busing probe can be inserted into the load break, and then connect the vice grips to the bushing probe, or an MC elbow adaptor can be used to connect to the load break. Finally connect the high voltage return lead to the concentric neutral in the system. With our connections properly made we can begin the basic mode test sequence. To begin the test sequence we want hit "Test Cable". The TDR will prompt to user if all the cables have been properly connected to the system to be tested. If so press "next". At this point the TDR will send a low voltage impulse through the cable seeking impedance changes in impedance and will automatically locate the end of the cable and provide the length of the cable under test. Next, the user is prompted if they are ready to thump at 8kV and should press "Next" if ready. Upon pressing "Next", the capacitor will begin to charge and then discharge at the selected voltage sending a high voltage impulse through the cable under test. Once the 5250 discharges, the high voltage impulse is depicted by the red line and the negative inflection represents where the fault is. The TDR will determine where the fault is and display that a fault has been found at "X" feet. Next, the unit will then prompt the user if they are ready to listen for the thump. Once the 5250 begins discharging, the other individual who is listening for the thump can begin pinpointing the fault using the HIPOTRONICS flash-phone listening device. Now that the cable fault has been pinpointed the cable can be unearthed and repaired to return service to customers. Now we can shut down the unit as well. Press "shut down" on the TDR, then select "yes" if you wish to shut down the system. Now that the TDR has been powered off we can also hit the power switch on the capacitive discharge portion of the unit. That concludes our demonstration of the 5250 in basic mode operation.
