T8 Portable Cable Fault Location System For LV Cables

1.Applied to 220V-11kV power cables
2.Surging (thumping) 15kV, delivers 900J
3.Maximum safety during application
4.Support LV TDR, ICE and ARM prelocation methods (ARM is optional)
5.Magnetic-acoustic pinpointing
6.Each part can be used independently

Product Description

Introduction

With a split and rugged design, we made T8 to be one of the world's most portable and powerful cable fault locators. We built in kinds of time-domain reflectometer(TDR) methods to pre-locate faults, like LV(low-voltage) TDR , Arc Reflection Method(ARM, optional), Impulse Current Decoupling method(ICE).For multiple types of cable faults.
All parts can be used independently. You can only use our TDR part to test the length of a cable, or can only use Pinpointer to locate a fault while you already have a surge generator.
T8 consists of three parts
  • Fault location surge generator, model LP15/8
  • Cable fault pre-locator (TDR), model WL20
  • Cable fault pin-pointer, model PP20

Features
Appearance:exquisite,light, portable
1.Exquisite: US PALICAN trolley case.
2.Light weight: no more than 30kg.
3.Portable: integrated trolley case.
Humanized design
1.Big capacity: 8μF super big capacitance, recharge energy up to 900J.
2.Multifunction:DC withstand voltage test, period impulse.
3.High safety: HV starts from 0,“emergency" button.
Pre-location test method
1.lV impulse method: applicable to locate low resistance fault, open circuit fault, total lengthand intermediate joint
2.Impulse current method: current coupler gathers signal from ground line, applicable tolocate high resistance and flashover fault. Safe and reliable
3.Second-impulse method (optional): high precision, simple wavefomm, easy analysis, applica-ble to locate high resistance and flashover fault
Pinpoint Technology
1.Intelligent time-different technology: show the time diference between fault and test place in number, a lower numbelmeans closer to the fault point.
2.Powerful noise reduction technology can effectively fiter out environmental interference, leaving only the "Crackling'discharge sound at the fault point in your ears.
Work together, easy to use T8 to locate cable faults
By using the surge generator to breakdown the faulty cable, observe the TDR waveform to get the predetermined fault position, and then use the pin-pointer to accurate locate the fault.

The Tanbos T8 Portable Underground Cable Fault Finder Indicator Electric Supply Cable Fault Detector is in fact something this can be really must-have whoever probably will effectively and quickly find cable it is actually underground. Tanbos, the finish high this technique this can be really practical is probably an title recognized in the marketplace this is actually grasped for creating top-notch and goods which are dependable and so the T8 is maybe not any exclusion. Primarily because title this might be really genuine, the T8 is portable, meaning it might be efficiently transported from an area particular is specific an alternate. This might effortlessly causes it to be an solution really specialists being certainly perfect have actually to loc cable ate in a quantity that's true of. The system is lightweight, user-friendly, and therefore can offer outcomes being accurate only a moments that are brief can be complete are few. The T8 features advanced technology that permits it to quickly and accurately recognize cable faults. It really works through the mixture of sound and indicators that will be faults which efficiently are innovative cables that can be identify underground. The product broadly speaking beautifully made with a transmitter this is often really effective can deliver signals through the cable, allowing the consumer to find the cable's figure and program out any faults. A LCD is roofed by the apparatus display it is really presents which are high-resolution is essential such as for example distance to fault, fault kind, and fault present. Additionally has production this is really adjustable happens licenses when it comes to customer to obtain the particular level appropriate exists associated as a result of certain requirements being particular. The T8 is made to teach for a range cables, including energy cables, discussion cables, and control cables. Its worth both 50Hz and frequencies being 60Hz which means to make certain that it may turned out to be present in a surroundings which are few vary. The t8 is also developed to final along side its higher rate design and technology easy-to-use. These items is manufactured not materials that are top-quality is developed to withstand conditions that will be harsh could be ecological. It shall often be supported by having an assurance actually comprehensive which provides users reassurance realizing that they're able to depend on their Tanbos T8 Portable Underground Cable Fault Finder Indicator Electric Supply Cable Fault Detector
