I am electrician of a basic level, talk about a few summary of 20 years in the job with everybody today.
Work 20 years, what make me vexed most is breaker tripping operation, every time very malapropos. May one pile a person round me, await me to solve a problem quickly, but everybody also knows, when just beginning occurrence problem, what information is done not have, often get urgently so sweating! Today, how does my general use at hand tool to solve most problem quickly with everybody discussion.
Summarize
We are a function that explains pincerlike watch with Fluke376FC above all.
We know, pincerlike the watch can be used at measuring circuit load. And can be used pincerlike the watch detects which breaker controls which electrical outlet, can help us solve laden problem quickly so.
Pincerlike watch guides through deciding electric current the magnetic field all round body will measure electric current. This we are in before introduced Huo Er in detail effect pincerlike is expressed and flexible the working principle that pincerlike expresses, if looking, can click look: Measure a principle.
Because configured an avometer function to test a line, watch of modern number pincerlike also has voltage and resistor to measure a function, use means and hand-held avometer are same. This is meant can use pincerlike the watch undertakes great majority is measured commonly daily.
If can use a kind of tool only,electrician is in in the job, optimal choice is use pincerlike watch.
IFlex is flexible a window that probe also is pincerlike watch. In basically can solving the stricture in the spot and congested wiring or space, measure the issue of wiring width. The IFlex that mark matchs is flexible voltaic clamp can expand alternating current span comes 2500A, watch letting clamp suits more to gauge demand.
In addition, pincerlike watch still has pattern of true virtual value. To it another corresponding kind measures mode is to be measured on average, cost is inferior, but the accuracy that measures electric current is not tall. Electronic load should exist on circuit only (drive of the computer, TV, illume, electric machinery, wait for) , the watch prohibits average measuring instrument possibly truly. Electronic load is bigger, not accuracy is taller. And the measurement that the pincerlike of true virtual value after calibration expresses the result is very accurate.
The breakdown platoon that builds electrical system is checked
Electrical engineering to the building, pincerlike watch is the necessary tool that measures load of each spur track. The voltage in electrical system is stable commonly, but electric current may change very big, may cause the overload of intermittence, cause circuit breaker thereby mobbish tripping operation. To discover the problem of these intermittence, what we must take electricity with clamp watch is the biggest with the least value, fluke376 can be used at capturing duration grows the tall electric current at 100ms or about 8 cycle.
One of building electrical engineering job common problem is socket and breaker correspondence rises, pincerlike watch suits to solve this problem particularly. Particular way:
1. is in the standard reading that measures the electric current before circuit is duped in switchboard.
Park of watch of 2. general pincerlike is the smallest / maximum mode.
3. inserts a load in place of the electrical outlet that be measured, for example blower, open its next 1, 2 seconds. (the bad news shedding of blower is 10-13A normally)
4. checks pincerlike watch, examine reading of the biggest electric current to whether produce change.
Difference of the electric current below normal circumstance should be very apparent. If reading is same, the specification did not find correct short-circuiting device.
Test leakage current
Leakage current can have been caused shed protector tripping operation, make motor and transformer overheat bring about equipment to malfunction, product line shutdown. We need to diagnose breakdown quickly, clearing up is to need to repair equipment or need to undertake simply changing.
Whether to put when leakage current on examination spur track, should mix live wire only 0 lines all park is pincerlike inside the gate of the watch, measures electric current is leakage current namely. Live wire and the electric current of 0 lines produce the magnetic field with opposite way. These two electric current are theoretic it is size equal, way is opposite, the magnetic field that produces should offset each other. If magnetic field is not quits, the specification is other the electric current with the constant presence on some access, the leakage current that be called.
If detect really leakage current, the electricity that and measure gets is very tall, have two reasons:
1. may be put in wiring mistake, right now need is discharged one by one with clamp watch check;
The insulation of 2. load is bad. Winding wears away or the electric machinery of clamping apparatus moisture is common breakdown cause. Can use insulation instrument to undertake impedance test is examined further at this moment.
Insulation instrument
Insulation checks to examining leakage current and equipment are isolated from very useful, but a lot of a lot of experts that discharge barrier feel embarrassed admit they often do not check insulation.
Is this why?
Often be 5 to 10 technician common an insulation instrument, additional as a result of insulation instrument price costly, volume is larger, and only, the function is single, because this is not normally,be the one part of individual kit.
Be compared and character, fluke1587 insulation avometer suits very much carry inside kit. They with a number multi-purpose the dimension of the watch and price, provided a number multi-purpose all and electric function discharging barrier of the watch, adscititious insulation checks a function.
In addition they return accessary and crocodilian clip commonly, thermocouple, test pen, these combination are used very conveniently. The protective cap that checks a pen especially shows the needle that checks a pen only, the avometer with more general phase is shown grow long test shot, can wait for an environment in electric equipment ark, circuit board so unapt hand shakes lay a finger on to arrive when the test fasten yuan of parts of an apparatus sutural the accident that causes the hazard such as short circuit happens.
Had appropriate tool, when undertaking checking for the first time won't problem of miscarriage of justice, so can better diagnostic breakdown.
Summary: No matter be the residence or other test, pincerlike watch and insulation test tool are the test tool with indispensable electrician. Kit mark matchs Fluke376FC pincerlike watch and Fluke1587 insulation instrument, conduce to promotion work efficiency, solve real problem quickly, on the safe side
