EVA-H (Harmonics Meter)
EVA-H, complete microprocessor based, poly-phase harmonic meter
is equipped with high-resolution liquid crystal display to complete
its new state of the art outlook. EVA-H is an ideal meter for
each switchboard where load consists of non-linear loads. EVA-H
gives Total Harmonic Distortion (THD) for current & voltage
and complement for other EVA series products. Harmonic distortion
is widely reputed as culprit for cable failures, premature transformer
failure as well as abnormal tripping of protection relays. Therefore,
it is really important to find out harmonic distortion level at
every feeder in the plant. Earlier this is expensive exercise
but with EVA-H, plant managers can get all the harmonic information
with minimal cost. EVA-H is one of the most cost effective yet
function rich device with 2 in one concept (2 parameter easurement
in single device). We offer this solution with high accuracy class
of +/-1.0% and selectable CT ratio &
network configuration.
