How does a new upgrade in system help to overcome Limitations of the present system:

• The operation of the HTMC is quite simple concerning the overhead system. Isolation in the case
of HTMC is very quick and at the fingertips, and needs a single operation; whereas in the case of
the overhead system it carries out in three steps, as the DO fuses are put off by succeeding operations.
During the handling of the DO Fuses, there are chances by the swing of the DO fuse elements,
it may touch the MS parts of the structure leading to an accident or power supply which may cause interruption.
• In HTMC, the interlock provides between the operation of LBS and earth switch. This not only gives
An extra stitch of safety for operation but also the functioning of the entire system and the
• The HTMC provides an effortless mechanism for the replacement of the CTPT unit as it is done by the trolley
transfer method. The handling is simple and it does not require extra appliances like chain
pulley block. It shortens the time for the replacement of CPT.
• The HTMC with LBS provides exact protection by HRC fuses/ VCB against overhead do fuses.
• The HTMC is mounted on a well-constructed plinth. This provides a simple access point with
Respective of overhead lines. The operator is helped with the operation of the HTMC.
• The HTMC is strongly earthed with the standard earthen system. This enhances the life as well as
safety of the CTPT, human and animal as well. In fact, the solid earthen of the CTPT body is
a must-have condition. Whereas in the case of the overhead line the same get declined
by the passage of time. This can also cause consequences to the functioning of CTPT, in the case of the O/H system.
• In the case of HT installations, an energy meter needs to be installed just below the CPT unit. This may
Cause a very dangerous situation for the staff engaged in testing and vigilance activities.
Certain cases have happened where the outdoor CTPT have exploded resulting in fire, causing
The accident to the staff on duty or outsiders, which will be totally eliminated in the case of HTMC.
•As per the images of the HTMC, it is revealed that it gives the qualitative look for our
the highest revenue-generating HT consumers, safety, power supply reliability and pilfer proof
installation, as well. Consist of its Protection switchgear, Metering Compartment, and other accessories.
