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: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: 4, the average rated voltageRegulations, average rated voltage is about 1.05 times the network voltage, and appropriate rounding

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:Power equipment sales process, the customer asked the most questions thank you: 3, the component parts of the device, which is the core component of the device, to master the working principle of the device oh;4, after-sales service problems, technical introduction of after-sales service;5, price, product prices and other brand products at what level;

Q:The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!: The complete set of power distribution equipment is a complete set of equipment supplied by the manufacturer. The electric main circuit is divided into a plurality of units, each unit is a circuit, and the circuit breaker, the knife gate, the current transformer and the voltage transformer of each unit are connected

Q:What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?: Accident: has occurred, resulting in loss of damage,Such as short circuit arc circuit breaker tripping, burning, scrap.

Q:What is the power plant: Are you going to apply for technical workers or Gang Gang ah, technology is the design of scientific research work what, workers do more

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: Power equipment classification:1 the sequence of electric power in power system can be divided intoPower generating equipment, power generation equipment, power transmission equipment and electric equipment2 the main role of the power system can be divided intoPrimary equipment, two equipment

Q:In order to ensure the normal operation of the power system and equipment to achieve a grounding: 2) protection of grounding: is the electrical equipment in normal circumstances, such as metal parts, such as metal shell, structural frame and the earth to make metal connection. In order to ensure personal safety.3) security is zero: is the electrical equipment in normal circumstances without the metal part of the system and the zero line connection to avoid the risk of electric shock. For three-phase four wire system of electrical equipment, must adopt the method of security zero.

Q:The state of power system equipment is divided into four states: (1) running state. The isolating switch and circuit breaker of the equipment are in the closing state, and the circuit is connected between the power supply and the receiving end.(2) hot standby. The circuit breaker of the equipment is disconnected, and the isolating switch is in the closing state. (3) cold standby. The circuit breakers and disconnecting switches of the equipment are in the open position.

Q:What are the technical measures to ensure the safety of the power line equipment?: 5 hanging sign and installing fence (fence).These are the contents of safety regulations (line part)
