Specifications

MRD-196H series fault wire location device of low current adpots 80C 196 single-chip mirocomputer for analyzing, applicable to 0.38KV~66KV power system of unground or ground via arc-suppression coil as well as via neutral ground resistor. No matter metal grounding, gap grounding, arc flash grounding or accompanied ferromagnetic resonance grounding, it could accurately locate the grounding wire without limit to wire-out way (over-head line or underground cable line)

Introduction

TM500 Power Cable Fault Locator adopts international advanced electronic testing technologies and SCM technology, and combines low-voltage pulse reflection and pulse current testing methods, is suitable for the precise range finding of power cable high resistance, flashover, disconnection, and low resistance.

Low-voltage pulse reflection method applies to test the range of the low resistance and broken line, and the length and wave velocity of various cables. Pulse current testing method can be divided into breakthrough high-voltage flashover and DC high-voltage flashover for the high resistance and flashover cable fault finding.

Features

1.Combines low-voltage pulse reflection and pulse current testing methods, is suitable for the precise range finding of power cable high resistance, flashover, disconnection, and low resistance.

2.With high degree of intelligence, it can automatically determine whether the failure point discharge or not and automatically calculate the fault distance.

3.Compare with the traditional flash measurement instrument, which use resistance and capacitance divider measuring pulse voltage signals, the current sensor tests the pulse current signals in the grounding line with simple and convenient wiring, and good security with isolation of high-voltage equipment and the electrical circuit.

4.High testing accuracy:

When the distance < 1km, the test error ≤1m

When the distance > 1km, the test error ≤0.5%.

5.English menu, easy to master and use.

6.It can preserve 20 testing waveforms permanently, no loss after the shutdown, is a replacement of printer. With a clock logo, you can read waveform file easily.

7.Using a large LCD screen with backlight. Adjusting LCD display brightness through pressing keys.

8.Rechargeable nickel-metal hydride batteries, automatic charger management.

9.Small size, light weight, and portable design

Q: Would like to ask: railway communication, signal, power equipment installation related to mechanical and electrical engineering? If belong to, including specific aspects. Thank you: 3, in fact, including the power of the two professional: power and electrification. Including contact network infrastructure, post, wire rack, remote control, lightning protection system, station lighting intelligent control etc..Belong to the scope of the installation should be the station (communication station) equipment into the test, the basis of processing and installation, equipment installation, commissioning of the single body, the electrical subsystem Unicom debugging, the whole system of professional debugging unicom. And other railway professional with the commissioning test, etc..

Q: Is the GIS in the electric power high voltage switch cabinet: GIS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.

Q: What are the characteristics of the grounding of the power system and equipment?: According to the use and nature of grounding, it can be divided into "working grounding" and "security grounding".

Q: Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference: Here are a few concepts, you can check1, the network voltage, is the line or the rated voltage of the bus, which is usually said to be rated voltage, including 3, 6, 10, 35, 110, 3302, rated voltage generatorThe rated voltage of the generator is usually 5% higher than the rated voltage

Q: 1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?: The network equipment and the remote communication cabinet are responsible for the communication between the equipment and the background in the station and the communication with the electric power department

Q: Electric power equipment start-up and commissioning of the project there is a difference?: After a single commissioning, and then linkage test, after the test, such as no-load, put into operation in the above steps are completed, the test is no problem, start running with load.

Q: What are the two devices in the power system: . Such as measuring instruments, relays, switches, buttons, automatic control equipment, computers, signal equipment, control cables and some power supply devices, etc..

Q: Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations? For example, if the provisions of the housing construction warranty, you can check the "construction quality management regulations," but the warranty content of power projects, what information should be checked? Note that the warranty is not repair. Waiting for good people reply, satisfaction and then points.: This is not the regulations of state Power Grid Corp to their line of work area to do some local line area for engineering team to do is sign the contract established general warranty of 1 years seems to include tower structure, grounding resistance, line fitting, a line on what channel estimation problem in within the scope of the contract

Q: Pre checking and checking of goods in power system: Pilot: the full name of the preventive test, generally in terms of a power system equipment, in order to find in the operation of equipment problems, to prevent the occurrence of accidents or damage to equipment, equipment for inspection, testing or monitoring, including oil sampling test or gas samples. The preventive test is the operation of power equipment and to maintain an important aspect of the work

Q: What principles should be followed in power equipment maintenance: (2) the maintenance plan shall be arranged according to the unified arrangement of the power grid to improve the coordination and reduce the outage time of the equipment,. Improve operation reliability and equipment availability.
