its a device that checks the cable for crosswiring or short end. it also has a built in TDR ( Time domain Reflector ) wich tells you where the problem is and how long the cable is etc. It usally has an F connector and a RJ45 plugg.

How i can do Stability testing for restricted earth fault?
We can perform stability test on restricted earth fault by following these steps :- 1 - choose one phase of primary windings like phase R and make short circuit connection between phase R before CT ,and N after CT . 2 - Prepare primary injection current equipment and connect it's first cable on phase R after CT , and its second cable at any earthed conductor near Neutral . 3 - start injection current up to 100 AMP , if the relay isn't trip , this mean the system is stable ,Also if the relay operate which mean there is a fault in connections which must be modified . with best wishes ...

What is a bus fault?
When a fault occurs in the electric bus (electric lines and intersections) due to short circuit between the phases or between 1 or more phase and ground, the current value mounts up to a very high value, which is known as bus fault current. This high value of current may cause damages to the transformers and could also rupture the other electric lines connected to the bus.
How does a hand crank winch make work easier?
The handle on the crank is a essentially a Lever. It makes it easier to pull in heavy loads on the cable attached to the winch.
What is the difference between baseband coaxial and broadband coaxial cable?
The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.
What is the function of the simple pulley machine?
The function of the simple pulley machine is the transfer the amount of force by utilizing a cable of sorts to lift while the other side is pulled. Simply put, when on side is pulled down, the other side is lifted.
What will happen when a single cable is at fault in any topology?
Mesh topology- a cable at fault not affect others. Ring topology- a cable at fault, only affect side by side, If main cable at fault ,whole system shut down. Star topology- a cable at fault, others are not affected. If Hub at fault, whole system shut down. Bus topology- main cable at fault, system will shut down. a cable at fault,will not affect others.
The following fault should be found on flexible cords and cable with the exception of?
The fault that should not be found on flexible cords and cable is the ground fault.Faults that should not be found on flexible cords and cable is the ground fault.
Tone generators and tone locators are used to determine characteristics about a cable?
Tone generators produce a signal that can be detected by a tone locator when attached to a cable. This is useful for identifying cables in a bundle, tracing their routes, and determining cable faults or breaks. The tone locator helps pinpoint the location and characteristics of the cable such as continuity, length, and any interference.
Why armour HT XLPE power cable required to Earth?
because when ever fault current occurs then the cable wont get damaged due to cable armored earthing to the gland for fault current to pass through groung
How do you locate underground cable fault?
Time Domain Reflectometers can be used to locate where an underground cable fault lies. Time Domain Reflectometry (See wikipedia) is a measurement technique to identify the location using reflected signals sent down the cable line.
SONETs extraordinary fault tolerance results from its use of a double-ring topology over fiber-optic cable?
Fault tolerance.
Using blavier test to check for cable faults?
This is use to locate the ground fault of a single cable. This test is performed with the aid of a low voltage supply with an ammeter or voltmeter. In this test the resistance between one end of the cable C1 and the earth is first measured with the other end, C2 isolated to earth and then with the C2 earthed. Let the two readings be represented by R1 and R2 rep! If r1 and r2 are the conductor resistance of the length of cable at C2 to fault and at C1 to fault rep!, and "r" is the resistance of the fault to earth
Which tool can you use to determine the distance to a fault in a faulty cable?
Time domain reflectometer
What is varley loop test?
A varley loop test is a test used to find the earth fault location in an underground cable. It uses the Wheatstone bridge to help determine the distance from the test point to a fault in a telephone or telegraph line or cable.
What kind of workers would use a cable locator?
People that install cable or other electrical wire would be the kind of workers that use this kind of tool. Utility companies all have these locators to make their job easier.
What part of speech is locator?
The word "locator" can function as a noun.
Why is my Samurai clutch pedal very stiff?
Stiffness can be from the cable being corroded or jammed full of mud. If the cable is not at fault then lubricate the clutch peddle axle.
