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: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.: According to the "construction quality management regulations," the fortieth: the scope of the warranty and its normal use of the corresponding minimum warranty period of 2 years.

Q:Large engineering construction (such as buildings, factories, institutions) distribution room of the power equipment as required? What's the difference? For example, some requirements never power, and some to eliminate harmonics to improve power quality, the more detailed the better the program: In the vicinity of the power grid in the supply of power on the requirements of their own generators to ensure that the dual power supply. Factories and institutions to see what the main work, if it is steel, hospital, such as the load category one or two categories of power needs of the dual power supply. And the load such as electric furnace, easy to produce harmonics, in order to ensure the power quality of the grid, it requires the installation of harmonic elimination device.

Q:What are the effects of frequency variation on power users and power systems?: Influence of frequency variation on power users and power systems:There is a close relationship between the frequency of power equipment and the operation of power system

Q:Is the GIS in the electric power high voltage switch cabinet: IS 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:We are a manufacturer of intelligent switching equipment manufacturers to bid in the power grid to say what is the first access to what the Department: State Grid procurement requirements to provide information: network card requirements are not standardized,For the national grid access card: 1, please hold valid company documents to the local GRID (NATION) business hall, consulting

Q:I do sales of electrical equipment, how to deal with the power supply bureau?: 380 low voltage line equipment (switchboard, overcurrent protector, etc.) or electrical equipment (such as electric energy metering, checking table, meter and electric meter box, etc.) if you want to make better cooperation effect you, if you have the ability, then of course you directly to the main leadership of the power department is better the.

Q:Electric power equipment start-up and commissioning of the project there is a difference?: The difference is that one is the equipment debugging, testing period to start, one is in the formal production of the time to start.

Q:How to strengthen the management of electric power information communication equipment: Problems in the management of information communication equipment1 personnel structure is not reasonable. With the continuous expansion of the power grid, power information communication equipment is also increasing. But at present, there are some problems in the management of electric power communication equipment, such as the lack of professional staff and the lack of post. At the same time, due to the lack of post phenomenon, resulting in the equipment management and maintenance work in the process of increasing the workload, making the existing staff complaints, work quality and work enthusiasm can not be guaranteed. On the other hand, because the new staff less power communication professionals confidence aging trend is more and more serious, the personnel structure imbalance restricts the progress and development of electric power information and communication equipment management to a great extent.

Q:What specific enterprises and units are used to test the power of the equipment ah: The other really did not ~ ~ ~ ~ ~What do you mean by electrical testing equipment??? High? Low?

Q:Recently went out to do the test, do not know the difference between the two tests: The purpose of the test is to test the performance of the equipment to prevent the occurrence of the fault, the former is the first time after the installation of the equipment to change the nature of the acceptance test, which is run during the routine. The content of the test items are different.You check the 1 power standards will know, since you do this test should have a standard hand.
