What is Static?
Electricity at rest.

How simple but inadequate this definition is of a natural phenomenon that is most capricious. It costs industry millions of rupees every year!

It's manifestations are familiar to all of us. In the form of lightning and it's aftermath thunder, static strikes into old & young alike. For the brief instant lightning flashes, static electricity is no longer at rest. There are many examples encountered in industry which cannot be dismissed as interesting, amusing or inevitable. Their effect can be to ignite, destroy, cause explosion or give fatal shock, create handling difficulties and spoil goods with dirt.

How can we control Static?
Basically there are two ways of controlling static:

• Temporary control by air ionizing devices. 

• Long term control by utilizing anti-static additives in primary manufacture of raw materials.

PARA Electronics' Role
For over 20 years, PARA is manufacturing range of static measuring & control instruments to fight the devil of static  encountered in the industrial environment.

The instruments conform to the recommendations per IS7689-1989 of Bureau of Indian standards. In order to solve static problem, three basic steps must be taken:

• Identify the problem :  The PARA Static Charge Meter will measure the amount and identify the polarity of static charge present. The meter will also help in checking effectiveness of ionisers /static eliminators. 
  

• Determine a Solution :  Once the problem is identified, solution should be considered next. Can the static be controlled by grounding, ionization or a combination thereof. PARA offers air ionizing electrically powered static control equipment. This type of equipment is most effective in neutralizing static during manufacturing process. 
  

• Selecting proper equipment : Selection of a proper ioniser is most important. PARA offers a wide range of ionisers to suit every application. These ionisers are powered by an electronically controlled HV power supply. 
  PARA's role is not, however, restricted to standard products. Possibility of using new designs as well as investigating problems is always under consideration.

Static Charge Meter SCM-1

As the requirements for static protection and control have grown in recent years so has the need of measurement equipment to monitor static charge. Location and measurement is the first step to control static. Static Charge Meter provides fast easy measurement of static charge, locates the source static charge and identifies the polarity.

SCM-1 is compact lightweight, battery-operated, non-contact type unit. It is easy to handle and enables quick detection and measurement of static potentials.

SCM-1 is certified intrinsically safe by Central Mining Research Station, Dhanbad, for Group I, IIA & IIB hazardous areas. 

Elimination of Static Electricity

Ionisers effectively neutralize static charges of either polarity through ionisation of surrounding atmosphere. Ionisation is achieved by AC high voltage corona discharge. Ions of either polarity are generated. Different types of Ionisers can be connected to the control unit. We offer range of Ioniser to suit customer needs.

Static Charge Controller

Static Charge Controller is a mains operated electronic control unit and generates AC high voltage supply to drive ionisers. Different types of ionisers can be connected to the control unit.
