How to install electricity meter : the meter installation certificate

act Type

Today electric appliance measuring the consumed electric power can not be installed without the accompanying documentation, moreover, it is obligatory to act installation of the meter.This act shall be signed by two copies and regulates the standards and the installation of electric meters obschedomovyh rules.To make it a little more understandable is to talk about the components of this act.

example act on the next photo.

So what comprises a document that serves as proof of the legitimacy of any instrument?

1. Count, which we shall call "the installation."In this chapter, signs connection name (ie, feeder), where the counter installation took place.This may be some kind of substation (typical entry in chapter looks something like "substation № 8, p. 9").
2. Count type, serial number, code release and accuracy class.Naturally here you write, what type of device, serial number and year of manufacture.Also, be sure to indicate what was the accuracy of the previous, and which is now set.
   
   typical entry for this columns: "Out of the two-phase counter-SAZU IT inductor, number 19076564, 1956, accuracy class 2.0."
3. state inspection sign.Graf takes into account the date and the last quarter of State monitoring, which was carried out on the installed meter.
4. Information from the counter.Indications of active and reactive energy meters are written off from both, and shall be entered in the act of installation.A typical entry:
   «SAZU-IT - 765.56 (kW • h)
   SET-5TM.09M.03 - 0.00 (kW • h), 0.00 (kVAr • h)."
5. coefficients calculation.
   For example, the meter is installed with two current transformers that have Ktt ratio = 500/6 and voltage transformer NTMI-10 with KTN coefficient = 11000/100.Here is the multiplication factor of the first to the second.And all indications are multiplied by this factor.
6. energy that exclude.
   During the replacement of the device, a certain amount of energy is not uchlos during the settlement period, this is the place to fill these data.
7. reason that you decided to replace the electricity meter.For example, it can be the previous excision tool life, poor accuracy level etc.

At the end of the filling instrument electricity meter installation certificate, you must specify which terminals are on the counter.Then plombiruem packaging with a record of the place of filling, filling the room, the organization name.

Installing device

Then a closer look at some of the rules of the electricity installation.

1. desktop document when a new device is the SAE "Rules for Electrical Installation."And it is only right rules installation of electricity meters.
2. Determination period last state inspection device in a private home or apartment.Inspection date appears on the seal of the counter.The print date appears in the form of Roman numerals denoting the quarter and the year of verification.
   ago Check for three-phase meters - should have a statute of limitations does not check more than a year, and the single-phase - no more than 2 years.



3. installation.Connecting the electricity produced in a private house at a height of 1-1.7 meters from the floor and often taken place at eye level for easy readings.
4. the electrical work.According to regulations, permits, switchboard operation should not block all kinds of plates, niches, cabinets, etc.A simple and convenient access to the counter - it is almost a guarantee of its long work.Installed under a slope of 1 degree.Permission is mounted on wooden, metal and plastic plates.



5. Fill act of installation of the meter, how to do it, you know.
6. switching device can be installed at a distance of up to 10 meters, and control fuse and metering devices using it.Tension thus removed from all phases of the counter.The only discomfort in the form of the control systems are error power supply companies in which your accounting device may look like a kidnapping.

Good luck in operation, be vigilant and pay utility bills on time!
