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: 1 what is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3
- The rated voltage of the electrical equipment is the working voltage standard designed by the designer.4, the power system uses a variety of voltage levels, on the one hand is the process of historical evolution, in 50s only 35KV, in 60s with 110KV, in 70s the establishment of the 220KV power grid, and later developed to 500KV and DC transmission. On the other hand, a higher voltage level is used to further the safety and economy of transmission. Of course, the retention of 35KV and 110KV, but also taking into account the economic costs of close range transmission.
- Q: Recently went out to do the test, do not know the difference between the two tests
- Preventive testing is to test or test equipment periodically and regularly. For example, once a month, 3 months or a few times a year of preventive testing or testing, to exclude the existence of hidden dangers...
- Q: What power equipment is needed for the motive,
- There are many steps in engine manufacturing, including parts manufacturing and engine assembly.
- Q: What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?
- Exception: may be a precursor to the accident, has not yet caused the loss, the cause is unknown,Such as the normal operation of the cable overheating, burning plastic taste
- Q: Under the same voltage level, the rated voltage of the equipment is not exactly the same
- And some appliances have no effect. For example: switching power supply, it can work in a wide range of voltage, the output voltage remains unchanged. It should be noted that, as long as the manufacturers in the normal operating voltage range, generally will not cause the state of work and security issues, can be assured that the use of.
- Q: What are the necessary equipment for power line project?
- First of all to have safety equipment, such as an electroscope, grounding wire, personal security line, an insulating rod, a nuclear phase device etc.
- Q: How long has the power of power electronic equipment delivered water
- Pneumatic conveying device has good dustproof effect; easy to realize mechanization and automation, reduce labor intensity, saving manpower; in the transport process, can be a variety of technology operations at the same time, such as mixing, crushing, sorting, drying and cooling; to prevent the material moisture, pollution or mixed with debris and other advantages, so it has been applied in the casting department, metallurgy, chemical, building materials, food processing etc.. Its main disadvantage is that the power consumption is large
- Q: Power test equipment sales to find power supply company which departments? Which departments of the power supply company will use the power test equipment?
- What kind of power test equipment are you in charge of? Our unit is divided into the experimental class and the automation experiment class
- Q: Definition of power equipment defects
- Personal opinion: defects and hidden dangers have certain differences, can not be equated with the...
- Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
- That response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power, get rid of the accident or the narrow scope of the accident to
