Maximum demand meters are intended for testing momentary thermal load of transformers, cables, electrical machines etc. The bimetallic movement responds and indicates the mean RMS current loading over a specified period of time. A black pointer which is attached to the bimetal spiral moves in response to the current -(heating) in the bimetal spiral. A red pointer (slave or memory pointer) is driven by the black pointer. The red pointer remains at its maximum position to which the black pointer has reached during any period of time. Further, when the loading is reduced, the red pointer remains at the maximum value. This enables the operator to know the maximum loading of the system without continuously watching the meter. A zero corrector is provided on the front of the meter to bring back the red pointer to the position of the black pointer. A sealing/locking facility is also provided on the zero corrector to prevent tampering of the reading at the red pointer. This series products have electromagnetic and magneto electric two types, which is applied for control system or power distribution system to display the corresponding electrical parameters, such as AC/DC current, AC/DC voltage, power factor, Hz, etc.

 

Model Name ST-96 and ST-72
Accuracy class: 1.5
 

For through current higher than 40A ,

Accuracy class is 2.5

Specification of ammeters

for through current :

0.1A 0.5A 1A 1.5A 3A 5A 10A 15A 20A 25A

30A 40A 50A 60A 75A 100A.(Notice:For through current higher than 40A

,Accuracy class is 2.5.)

Specification of ammeters

for transformation ratio :

The meters should be used with a current

transformer of which primary current is 10A

15A 20A 25A 30A 40A 50A 60A 75A 100A

20A 150A...10KA and external secondary

current 1A or 5A. As long as overload rate

and the incoming current keep the same,

dial scales of all types in this series can be

exchanged yet remain the accuracy.

Overload rate of Ammeters:

1.non-overload 2.1.2times 3.2times

4.5times

Specification of voltmeters

for through voltage :

30V 50V 75V 100V 120V 150V 200V 250V

300V 400V 450V 500V 600V

Specification of voltmeters

for transformation ratio :

The meters should be used with a voltage

transformer of which primary voltage is

400V 450V 500V 600V 1000V 1500V 2000V

3000V 5000V….450KV and external

secondary voltage 100V

Overload rate of voltmeters : 1. non-overload 2.1.2times
Product performance:

All the meters are equipped with pure white

silk-screen printing dial scale.The

movement is made of intensive PBT plastics

and permanent magnet steel so that it is

vibration-resistant and heat

resistant.The case is made of ordinary ABS

plastics or flame retardant ABS plastics ,of

which the resistant temperature can be up

to 85°C.The base is made of PC plastics or

flame retardant PC plastics,of which the

resistant temperature can be up to 120°C .

The resistant voltage is higher than 2000V.

This kind of meter is easy to install with

high-strengthen plastics grip piece by

screwing down the nut so that the meter is

of high immobility.

Principles of measurement

and the features:

Each electromagnetic meter consists of a

magnet coil with a static sheet iron inside

and a moving sheet iron with a tractive

balance spring. When current flows through

the magnet coil,magnetic field appears.

Under such circumstance,the static and the

moving sheet irons are magnetized

simultaneously and remain the same

polarity. According to the theory that the

same polarities repel each other,repulsive

force between the two irons makes the

pointer deflect.When the torque and the

restoring torque keep a balance,the pointer

on the moving iron will point to a scale

mark,which is the measured value.

Usage of the electromagnetic meter The electromagnetic meters can be used for AC circuits under ordinary circumstance as well as for DC circuits instructed with TRMS. The structure of this kind of meters is simple,yet the accuracy is high,as well,they can be used for 50Hz/60Hz circuits. Special frequency should be marked out when the order is placed.
