PART 2 - PRODUCTS
2.1 MANUFACTURERS
A. [The medium voltage power meter shall be type SIMEAS P by Siemens or pre-approved equal. Approved manufacturers are as follows:
1. SIEMENS
2. . ]
2.2 COMPONENTS
A. Power Meter
1. The meter(s) shall be panel flush mounted & provide following functions:
a. Measurement of voltage, current, active & reactive power, frequency, active & reactive energy, power factor, symmetry factor, voltage and current harmonics up to the 21st and total harmonic distortion
b. [Extended measurement memory 1Mbyte. [Optional depending on order selection]]
c. [Battery [Optional depending on order selection]]
d. [Real-time module measured values and states will be recorded with time stamps. [Optional depending on order selection]]
e. Single-phase, three-phase balanced or unbalanced connection, four-wire connection
f. PROFIBUS-DP or MODBUS RTU/ ASCII communication protocol.
g. Simple parameterization via RS485 communication port using Windows XP software program.
h. Graphic display with background illumination with up to 20 programmable screens
B. Selectable Screen Types
1. 2 or 4 measured values in one screen
2. One list screen for minimum, average and maximum values
3. Two types of screens for harmonics
4. One screen for oscilloscope function (sampled values or R.M.S. values)
5. One screen serving as phasor (vector) diagram
6. Up to 20 screen types can be programmed. Switching from one screen to another can be automatic or manual
C. Memory Read-Out
1. Separate functions integrated in the configuration software, enable a read-out of the following information:
a. Mean values
b. Mean values of power
c. Oscilloscope recordings
d. State information of binary channels
e. Limit value violations
f. Log entries
D. Display and Evaluation
1. All values and information read out via the software are shown automatically in tabular and graphical manner together with the time stamp on the screen. The context menu offers some functions (masking of signals, copy, zoom, measuring functions) for easy analysis of measured values and state information.
2. The following measured values can be shown in graphical manner:
a. Mean values
b. Mean values of power
c. Oscilloscope recordings
d. State information of binary channels
e. The following information are shown in tabular form:
f. Limit value violations
g. Log entries
E. Export Function
1. The software also enables a function for the export of transmitted values and state information into an ASCII file. This ASCII file can be used in other applications, e.g. MS-Excel. Oscilloscope recordings can be exported into COMTRADE formatted files.
