MW Meters, Analogue Type

GENERAL :

“INDOTECH” Watt, VA, VAR & Power Factor Meters are available in following type :

1. DYNAMO METER TYPE :

   Current Coil & Volt Coil interact to give direct reading on dial.

2. TRANSDUCER TYPE :


    Electronic Transducer gives signal in terms of DC microamps to moving coil DC meter which gives reading proportional to the       signal.

‘‘INDOTECH’’ WATT / KW / MW METERS :

Wattmeters are meant for measuring effective power and are designed for single phase as well as three phase balanced & unbalanced loads

‘‘INDOTECH’’ VA/KVA/MVA METERS :

VA meters are meant for measuring Apparent Power in 3 phase systems.

‘‘INDOTECH’’ VAR/KVAR/MVAR METERS :

These are used for measuring wattless component of VA in 3 phase systems.

‘‘INDOTECH’’ PF METERS :

P.F. of a circuit is the ratio between the effective power & the apparent power and is measured with the help of a power factor meter.
