We are one of the leading manufacturers of Energy
Saving Equipments related to industrial, commercial and power distribution
applications. We have a rich & vast experience spanning over 20 years in this
field. We are the pioneers in introducing the concept of Real Time ultra fast
Automatically Switched Thyristorised APFC System, for reactive power
compensation. Over the years, we have offer our products and services to
Electricity Utilities, leading industrial units and other customers and have
build up a healthy customer base. With our commitment to continuous improvement
in our products and services, we have developed our own market reputation. APFC
Relays with the best technological features, which are definitely in a class
apart from other Relays available in the market.
PRODUCTS & SERVICES:
The products and services offered by GB CONTROLS are
mainly oriented towards Reactive Power Compensation and strengthening the Rural
Electrification Distribution Network, which has been emphasized as Topmost
Priority Plan by the Central Power Ministry based on principal that “ENERGY
SAVED IS ENERGY GENERATED.”
Presently the activities of GB CONTROLS include
the following manufacturing and marketing products:
1) Automatic Power Factor Control Systems using
the following technologies:-
a) Hybrid (Thyristor + Contactor) Switched APFC
b) Thyristor Switched including Real Time APFC
c) Contactor Switched APFC Systems.
2) Harmonic Survey:-
In electrical installations where the harmonic
elements are higher than the internationally accepted limits, the instances of
failure of switchgear, cable & capacitor are very high. It is necessary to
assess the level of harmonics, both voltage & current, in any electrical
installation, so as to take preventive measures by installation of suitable
filtering circuits. We undertake detailed harmonic surveys and offer solutions.
3) Energy Auditing:-
GB Controls is having expertise team of engineers
for energy auditing. We conduct such audits for electricity boards, govt.
organizations and private industries. In energy auditing activity, we conduct
study of electrical network, load pattern and requirement of reactive
compensation for energy saving. After completing the survey based on thorough
analysis of the collected data of above said parameters we suggest the required
quantity of Capacitor panels to achieve the desired reactive compensation with
4) Detuned Filters for Capacitor protection:-
We design and manufacture capacitor banks with
detuned filters for protection of the capacitors against harmonics, to be
installed in electrical installations where the presence of harmonic currents
are higher than the internationally accepted limits.
5) Static VAR Compensation:
We are in the process of developing IGBT based
Static VAR compensation technology have planned to commercialize this product in
about six month’s time. This would be a revolutionary step in the domestic
market, as this would change the whole concept and means of reactive power
6) Active Harmonic Filters:
We are also in the process of developing Active
Harmonic Filters, which would suppress harmonic at the source itself, thus
protection of total electrical system from harmonics, resulting in minimum
breakdowns and enhanced life of the installation.
EXPERIENCE AND EXPERTISE :
GB CONTROLS has supplied / are in the process of
supplying Automatic Power Factor Correction Panels as per details shown in the
List of Orders.
We have supplied Thyristorised APFC panels of
various ratings to MES, MTNL, Radio Mirchi stations, National Board, Most of the
software parks, Call Centers, IDBI Banks, Renowned industrial organization,
Compton Greaves ltd. Aurangabad etc.
We would like to especially mention here that we are
carrying out most of the of Development works from system design to software
program & perform on site with system construction up to commissioning for the
companies, which are very well known as APFC manufacturers.
Also supplied 150 Nos 50 KVAr Thyristor switched
Systems to Maharashtra State Electricity Board (M.S.E.B) Aurangabad Circle.
In past, we had worked with organizations, which had
same product range.
In addition to above we have our esteemed customer
base in Mumbai, Pune, Delhi, Hyderabad, Bangalore, where we have supplied and
successfully commissioned around 300 systems which are performing very well.
This shows that the Company has experience and
expertise in manufacture, supply, installation and maintenance of Automatic
Power Factor correction systems using any of the switching technologies as well
as it has the technological capability of manufacture single systems of such low
ratings as 27 KVAr right up to 1000 KVAR.
GB Controls have a practical base engineers team to
work with current supply distribution network , which is a challenge to design,
built, install & commissioning the system with fluctuated supply voltages,
unbalanced load, variable power factor for the same type of load pattern.
GB Controls is committed for its results, services
after sales, new development, good touch with current, advanced technology &

KEY FEATURES OF GB CONTROLS APFC RELAY
APFC Relay is the Brain, Heart and Mind of the
APFC System. We employ FCP based Microprocessor
system, to monitor, measure, compute and command
operations. A few novel features and advantages
available in our APFC Relay are:
- Ultra Fast correction time.
- Four Line, twenty character backlit LCD
display for easy monitoring.
- Monitoring and display of maximum energy and
- A built in memory module which can store
various parameters upto 45 days.
- RS-232 Interface for data
downloading/instantaneous print out.
- Data downloadable to a HHU or PC or Laptop.
- All operations through membrane keys only.
No need of selector switches and ON/OFF
switches. However, can be provided in case
An additional and most advanced feature of our APFC
Relay is that it has got the optional facility of GSM connectivity. With the GSM connectivity the
status of an entire substation can be monitored from
a central monitoring station. It can also generate
status report on SMS mode and send hourly status
reports to a predetermined cell phone. Through GSM
connectivity with the remotely located controller,
various electrical parameters of controller are
The GSM Module access meter data and / or stored
metered data and transmit it to remote central
server database for access of metered data on the
internet with suitable password and user id through
Following are the key display parameters of the
Our APFC Controller is type tested for operational &
performance parameters from reputed Government
recognized test laboratories like;
