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: Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed
- 10KV below the district power equipment installation: tender units need at least a business license qualification certificate (Level 3 or above) safety production license,
- Q: No concentrator can be copied directly
- There are two types of remote meter reading devices in electric power generation: one is low voltage set, called concentrator, the other is called terminal. The concentrator role is the number of meter data, first by the carrier or 485 communication way to collect the equipment, and then through the cable (optical fiber) or wireless network (cdma/gprs) transmitted to the main station.
- Q: What power equipment is needed for the motive,
- As long as the hydraulic pressure machine, bearing induction heater, tooling, assembly line assembly, commissioning test bench. Large parts to a lot, such as various parts of the fixture, the assembly line to the rotary table, lifting operation, pneumatic tools, etc.......
- Q: The problem of electric power equipment withstand voltageWhy does the pressure decrease when the altitude is high? The air is thin, is not easy to breakdown (vacuum breakdown is not very low atmospheric pressure)
- Because of the low air pressure in the air at high altitude, at the same voltage
- Q: In order to ensure the normal operation of the power system and equipment to achieve a grounding
- 1) work: grounding is to ensure electrical equipment in normal or accident conditions reliably, the neutral point directly or through special equipment (such as Petersen coil, reactor, resistance, breakdown insurance, etc.) do metal and earth connection.
- Q: Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines
- Power equipment including: boiler, steam turbine, pump, deaerator, condenser, generator and so on, from the impact of steam boiler turbine blade hot out of the turns, then drives the generator to rotate to generate electricity, in general, now in thermal power plant and a large Shipping Co to use steam turbine
- 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: For example, EPS emergency power supply and so on, as well as those used in public emergencies.
- High / low voltage switchgear, power distribution cabinets, industrial ovens, constant temperature and humidity test box, ovens, air curtain machine (invisible door), inductive automatic door, air conditioning and industrial fans, NELL thyristor module, thyristor, single / three-phase bridge rectifier, fast recovery module
- Q: What is the redundancy of electrical equipment
- Redundant system accessories:1, powerDual power supply system is widely used in high-end server products, the two power supply is load balancing, i.e. when the system is working for their system to provide power, when a power failure, another power will bear all the load. Some server systems to achieve the DC redundancy, and other server products such as Micron's NetFRAME 9000 to achieve AC, DC full redundancy.
- Q: The relationship between primary equipment and two equipment in power system
- 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.
