Maintenance Free Earthing System
A well-designed earthing system is the primary line of protection for any electrical/electronic installation from
destructive fault current.The grounding/earthing system offers a low impedance path to the fault current resulting
into the safety of personnel and equipment.
As per IEEE 80:2013,
“A safe grounding design has the following two objectives:
- To provide means to carry electric currents into the earth under normal and fault conditions
without exceeding any operating and equipment limits or adversely affecting continuity of service.
- To reduce the risk of a person in the vicinity of grounded facilities being exposed to the danger of
critical electric shock.”

The National Electrical Grounding Research Project (NEGRP) was a project conducted by the National Fire Protection
Association (NFPA) Research Foundation.The objective of the project was to compare the long-term performance of
different types of earthing rods. According to the project, several different types of earthing rods were buried in
different types of soils.After 10 years in the year 2003, one of the original sites (Pawnee) was excavated and the rods
were removed.It was found that the copper bonded rod was virtually free of corrosion while the galvanised rod showed
significant deterioration.The UL listed copper bonded ground rods have served the industry exceptionally well,
providing a 40+ year life, typically 4 times that of galvanised ground rods.

covered in dust and as was the entire SPD
unit. In discussion, it was found that no one
was even aware of the necessity of SPDs
periodic inspection and hence, yes we can say,
the system was working without any kind of

Our conclusion-
We embedded a Red Light on it to indicate that the surge protector needs replacement.
Our engineers came out with the above solution and employed an additional feature of
green light (LED) to provide indications of, when the system is functional and in
contrary the red light indicate when it is need to be replaced.
Now some of our range of SPD’s are equipped with LED indications so that our
customers can easily manage their systems and continuous protection as assured.

A heavy surge can destroy a device in one
strike but can last for years in a protected
environment. So, there is a requirement of
some intelligent and graded indication such
that a planned maintenance routine can be
implemented and continuous protection can
be assured.
Our Solution:
To ensure this, we have innovated a way to monitor the
deterioration and a measure of the remaining service life of the
device and to show timely replacement of devices for consistent protection of
equipment and continuity of service.
Kindly have a look on this range of SPDs that are now equipped with feature of

There are three main types of EV charging – rapid, fast, and slow. By chargers we
meant the power outputs, and therefore the respective charging speeds. Rapid charg-
ers are one of two types –AC or DC. Both chargers will charge the majority of EVs to
80% in around 30-60 minutes (depending on a battery capacity).To serve the purpose,
we have charging stations that can be categorized at different charging levels- Level 1,
Level 2 & Level 3. Level 3 equipment with DC Fast Charging technology, charges
through a direct-current (DC) plug. Most Level 3 chargers provide an 80% charge in
30 minutes via a connector cable supplied with the vehicle.This also enables ultimate

Introduction
A lnfltable tower is a piece of mobile equipment which has one or more high-intensity electric lamps and a
mast. Almost always, the lights are attached to the mast, which is attached to a trailer, with a generator set to
power the lamps. Normally the lamps are metal halide bulbs and the generator is powered by a diesel engine.
However, battery-powered, solar-powered and hydrogen-powered sets are available; light towers
with electrodeless lamps lighting are also sold. Modular kits permit separation of the generator set, trailer,
lights and mast from each other. Another variation is an inflatable mast. Particularly when an inflatable mast is
used, the lights may be placed close to the ground, with a reflector attached to the mast. When soft lighting is
wanted, an inflatable "balloon" diffuser may be used. An inflatable mast may serve as a diffuser.
Light towers are used for construction. Some purveyors promote their use for other activities where strong,
temporary, outdoor illumination may be wanted, such as mining, motion picture production,
demolition, emergency services, oil refining, sport or agricultural sectors.
