Precision High Voltage Resistance Divider Type 5573A

5573A Precision High Voltage Resistance Divider 50 kV.
5573A Precision High Voltage Resistance Divider 100 kV.
The Divider has been designed in co-operation with the Electrical Research Association. 


It consists of 1MΩ resistors arranged in a
spiral about 30cm in diameter. 
The high voltage terminal consists of a
tapered plug inside a domed cap. 

The insulation is of Perspex and is of the order 
of 20 x106MΩ between sections. 
All connections are smooth and of uniform
diameter to avoid any sharp points of high
potential at which corona might occur.

The Divider is designed to have a resistance of 1000 Ohms per Volt and is made in 50 kV sections. 
The illustration shows one 50kV section mounted upon an earthed base with low voltage tapings. 

Each 1MOHM unit is wire wound and hermetically sealed. This construction provides resistors stable to a few parts per million with a temperature coefficient less than 10 parts per million per degree centigrade. 
The low voltage ratio coils are fitted inside the metal base to provide tapings at zero, 1V and 10V. 
The limit of error in the ratios is less than one part in 10,000. 
The divider is suitable for DC or power frequency work 50-60Hz. 

A safety device is fitted so that in the event of a high voltage flashover, the measuring equipment will be immediately earthed and the charge will go to earth and to the grading ring, preventing damage to the resistance network.
