New BAS standards adopted by translation method

The following standards were adopted into the BiH standardization system through the Technical Committee BAS/TC 10, Electrical energy measurement equipment and load control, by translation method:

 

- Second edition of BiH standard BAS EN 50470-3: 2017, Electricity metering (ac) - Part 3: Particular requirements - Static meters for active energy (class indexes A, B and C), is a translation of the English version of EN 50470 -3: 2006, Electricity metering equipment (ac) - Part 3: Particular requirements - Static meters for active energy (class indexes A, B and C).

 

 

This standard applies to newly manufactured static watt-hour meters intended for residential, commercial and light industrial use, of class indexes A, B and C, for the measurement of alternating current electrical active energy in 50 Hz networks. It specifies particular requirements and type test methods.

 

 

It applies to static watt-hour meters for indoor and outdoor application, consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s).

 

If the meter has (a) measuring element(s) for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces etc. are enclosed in the meter case (multi-function meters) then this standard applies only for the active energy metering part. 

 

 

 

- Second edition of BiH standard BAS EN 62053-23: 2017, Electricity metering equipment (ac) - Particular requirements - Part 23: Static meters for reactive energy (classes 2 and 3), is a translation of the English version of EN 62053- 23: 2013, Electricity metering equipment (ac) - Particular requirements - Part 23: Static meters for reactive energy (classes 2 and 3).

 

This part of the standard applies only to newly manufactured static var-hour meters  of accuracy classes 2 and 3, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this standard is based on the conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.

 

It applies only to static var-hour meters for indoor and outdoor application consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s). If the meter has a measuring element for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. are enclosed in the meter case, then the relevant standards for these elements also apply.

 

It does not apply to: var-hour meters where the voltage across the connection terminals exceeds 600 V (lineto-line voltage for meters for polyphase systems); portable meters; data interfaces to the register of the meter; reference meters.

 

- Second edition of the Bosnian standard BAS EN 62053-24: 2017, Electricity metering equipment (ac) - Particular requirements - Part 24: Static meters for reactive energy at basic frequency (classes 0.5 S, 1 S and 1) is a translation of the
 English version of EN 62053-24: 2015, Electricity metering equipment (ac) - Particular requirements - Part 24: Static meters for reactive energy at basic frequency (classes 0.5 S, 1 S and 1).

 

This part of IEC 62053 applies only to newly manufactured transformer operated static varhour meters of accuracy classes 0,5 S, and 1 S as well as direct connected static var-hour meters of accuracy class 1, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only.

 

This standard uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages only.

 

It applies only to static var-hour meters for indoor and outdoor application consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s). If the meter has a measuring element for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc., are enclosed in the meter case, then the relevant standards for these elements also apply.

 

It does not apply to: var-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems); portable meters; data interfaces to the register of the meter; reference meters.
