During the testing of Electrical Equipment the test cables
should not touch the equipments. For that testing engineers
use to cotton rope to hang the cable from measuring
Equipment to testing equipment terminal. Please explain the
technical reason for this practice.

Answer Posted / k.prakashchandra

This is done while meggering ,so that the measured value
will not be less, due to the proximity of cable with the body.

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses?  the second question is-generation is depends on LV winding? or LV winding design for generation voltage?

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
