PORTABLE METER





Description:

 

PORTABLE METERS: 

Portable meter can be moving coil, Moving Iron or dynamometer type and have method of indication by means of deflecting pointer only. These instruments are manufactured to meet the requirement of IS 1248/83.

 

CONSTRUCTION:

All the instruments are manufactured by the best quality material to give satisfactory performance over a long period. 

Portable meters are fitted in sun-mica wooden case with rubber footing and rexine strap provided with anti-parallax mirror and knife-edge pointer.

The moment is fitted on the Bakelite panel. The moment is secured between two saffire jewels. The precisely ground pivots are been used for minimizing the friction and sustain accuracy in vigorous field condition. The effective oil damping provides uniformly control torque and brings the indicating pointer to its final deflecting position without much oscillation.

All the metal parts are adequately plated to suit the tropical condition. Instruments are effectively shielded from external magnetic effects and electrostatic influences.

All the instruments have zero setting device in the front except power factor meters.

 

APPLICATION: Portable Meters are used for the measurements of the electrical quantities like current, voltage, Power (Active, Reactive) or the power factor of the network.
