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: What is the GIS in power system: Popularly speaking, GIS is often we can see the switch station, also known as high-voltage distribution device.There are three types of high voltage power distribution equipment: the first is the conventional air distribution equipment, referred to as AIS. The bus bar is exposed directly to the air, and the breaker can be provided with a porcelain column or a tank type. This type is used in Gezhouba Dam power plant.

Q: The production and transportation process of electric power: The equipment of the two system comprises a measuring device, a control device, a relay protection device, an automatic control device, a DC system and necessary auxiliary equipment. Power system voltage level has 220V, 380V (0.4 kV), 3 kV, 6 kV, 10 kV, 20 kV, 35 kV, 66 kV, 110 kV, 220 kV, 330 kV, 500 kV, 750kV, 1000kV. With the improvement of motor manufacturing process, 10 kV motor has been mass production, so the use of kV, 6 kV has been less than 20 kV, 66 kV is also rarely used. The power supply system is 10 kV and 35 kV. Transmission and distribution system to 110 kV or above. Power plant generator has 6 kV, 10 kV and, with a total of 20 kV, users are 220V, 380V (0.4 kV) low voltage system 20kV.

Q: Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?: . For example, according to the international standard requirements of the stage mechanical engineering life is 50 years. In fact, the service life of the equipment is related to the use of the equipment.

Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the equipment and equipment: The high cycle is high frequency, rated frequency of power system in China is 50Hz, the normal range was 49.8~50.2Hz, under normal circumstances, the power dispatching department through power planning, automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means,

Q: What is the installation equipment of the transformer on the power installation project: Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.

Q: Under the same voltage level, the rated voltage of the equipment is not exactly the same: The rated voltage of all kinds of equipment under the same voltage level are not completely the same as normal, different appliances the maximum withstand voltage is different, the design requirements of more electrical and marked a maximum voltage of 240V, some 250V. It is different from the actual working condition under different voltage (whether ideal and safe and reliable)

Q: I do sales of electrical equipment, how to deal with the power supply bureau?: I am in charge of power management and power management. To provide you with the following suggestions: both the high voltage power equipment (such as transformer, voltage or current transformers, towers, porcelain crossarm, netsuke etc.)

Q: What equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment: 3 from the degree of importance can be divided intoCore equipment and auxiliary equipment4 from the price can be divided intoLarge valuable equipment, general equipmentPower plant and substation electrical equipment is divided into primary equipment and two equipment. A device (also known as the main equipment) is the main component of the power system, it is the direct production, electricity transmission and distribution equipment, including power generators, power transformers, circuit breaker, isolating switch, power bus, power cables and transmission lines. The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer. The primary equipment and its connected circuit is called primary circuit. Two equipment in accordance with certain rules to connect to achieve some technical requirements of the electrical circuit called the two circuit.Relay protection and safety automatic device, dispatching automation and communication system are the two systems.

Q: How long has the power of power electronic equipment delivered water: ; equipment (mainly separator population) and pipeline (mainly elbow) wear faster, if the design, construction or improper operation, is easy to cause material deposition, so that the conveying jam, interrupt; transportation should not be high humidity, viscous or easily broken material etc..

Q: The relationship between primary equipment and two equipment in power system: The electrical equipment of electric power system is divided into the primary equipment and the two equipment, and the primary equipment (also called the main equipment) is the main body of the power system
