The presence of harmonics distorts
the waveform shape of voltage
and current, increases the
current level and changes power factor
of supply, which in turn creates so many
disturbances.
MECO "Power & Harmonics
Analyzer - Model 5850" is a state of art
versatile instrument using micro
controller technology and with various
functions that would be ideal for any
engineer/inspector for carrying out
vigilance checks, surveys, audits and
periodic visits for checking at industrial
and consumers end.
The measurements can be done on
live loads. it is able to do almost all the
analysis for single /three phase power
system and capable of analyzing it
standby power consumption to the
maximum demand of factory. It
calculates voltage and current of neutral
with respect to ground.
Large dot matrix LCD display with
backlight of 35 Parameters in one screen
to monitor energy, active power,
apparent power & reactive power,
power factor, energy, TRU RMS value,
AC current, and average demand &
maximum demand with programmable
time interval, CT & PT ratios.
It displays harmonics up to the 99th
order, THD with waveform with peak
value. PHA5850 displays power
parameters and harmonics of each
individual phase of current and voltage.
The analyser has features like real-time
graphic phasor diagram and also
captures 28 transient events with
programmable threshold (per cent).
MECO Power & Harmonics
Analyser Model 5850 has inbuilt
memory of 512K for 17,000 records
and optical Isolated RS-232 ~ USB
Interface with user-friendly software
for easy downloading of recorded data
are the key features of PHA 5850. The
analyser has facility to retrieve power
data & harmonics on meter screen.
