Compteurs de transducteur de puissance

APPLICATION
The PA39 power meter is a mowing-coil meter with a built-in measuring transducer. It is destined to measure active or reactive power in a.c. power networks. The measured power is indicated by a magnetoelectric (moving-coil) measuring system.
These meters are delivered in following versions:

  • - for measuring the active power in single-phase systems,
  • - for measuring the active or reactive power in three-phase three-wire or four-wire symmetrically or asymmetrically loaded systems,
  • - with the zero graduation on the left side of the scale for measuring the unidirectional power flow,
  • - with the zero graduation in the middle of the scale for measuring the bidirectional power flow.

CHOICE OF MEASURING RANGE
1. Calculate the power from the formulas:
P = Un X In for single-phase networks
P = √3 X Un X In for three-phase networks
where::
Un - network rated voltage:
• for three-phase networks - phase-to-phase voltage,
• when connected through transformers-primary rated voltage.
In - rated current
• 5 A or 1 A,
• when connected through transformers-primary rated voltage.
2. Round the calculated power value to the nearest value from the given sequence of numbers for the measuring range.
3. Example of measuring range choice
Three-phase network; rated values of transformers: 15 000/100 V i 400/5 A
P = √3 ´ 15 000 V ´ 400 A = 10,39 MW (Mvar)
Selected measuring range: 10 MW (Mvar)

FIXATION ON THE PANEL

One should prepare in the panel a hole at dimensions: 92+0.8 x 92+0.8 mm.
The thickness of the material of which the panel is made, cannot exceed 15 mm.
The meter is fixed in the panel by two screw holders situated on arbitrary opposite corners of the case.

ORDERING CODES

 

ORDERING WAY
In any order one must specify the name and the ordering code of the power meter using the tables: 1, 2, 3, and 4.
Order example: PA39 - H - F - O - L5 - 0 - O - 00 - 8, means:
H - Reactive PA39 power meter adapted to a three-phase four-wire symmetrically loaded network.
F - Network rated voltage: 3000 V (from table 3).
O - Frequency of the input voltage: 50 Hz (from table 1).
L5 - Network rated current: 300 A (from table 3).
0 - Unidirectional power flow.
O - Working position: C3, vertical (from table 2).
00 - Catalogue version.
