Application

These meters offer several advantages in switchboards and transformers Panels,used for measurement

of electrical parameters along with the threshold settings for relay operation.

ApplicationMovement

Moving iron movement has pivots of very high hardness. Movement is suspended between spring

loaded saphire jewels. Movement is critically damped by use of silicon oil.
