Therefore, till TANGEDCO first completes the first requirement of measuring the harmonic distortion, and finds a need to issue a three months notice, there is no obligation on the respondents 2 and 3 to fit the harmonic filters. The general notice dated 23.08.2013 merely makes a statement on the broad aspects of harmonic compensation, and when it has to be paid. The time however may run only from 24.12.2014, when the measurements were actually taken, which showed that harmonic distortion level exceeded the level prescribed under Regulation 6(ii). Now it becomes obligatory for TANGEDCO to have followed it up with the service of a three months notice on the respondents 2 and 3 herein, with a direction to the latter to fit harmonic filters. This is the second condition contemplated. But TANGEDCO did not issue any such notice immediately, but had taken another three months time since it measured the harmonic distortion on 24.12.2014, and chose to issue a notice only on 11.03.2015. The time therefore, will and can start running only from 10.03.2015 for the respondents 2 and 3 to fit the harmonic filters and this time was available to the respondents 2 and 3 till 10/11.06.2015. Here the respondents 2 and 3 admittedly have fitted a harmonic filter even prior to 01.06.2015, and informed the petitioner about it on that date. Now TANGEDCO took
