Rigorous Testing to boost efficiency in power substation

The measurement of insulation resistance is carried out to check the healthiness of the transformer insulation. This test is the simplest and is being widely used by the electrical utilities. This test indicates the condition of the insulation i.e. degree of dryness of paper insulation, presence of any foreign containments in oil and also any serious defects in the transformer.

The measurement of insulation resistance is done by means of Megger device of 2.5 kV for transformer windings with voltage rating of 11 kV and above and 5 kV for EHV transformers.

Type test carried out to prove conformity with their specifications these are intended to prove general qualities and design of a given type of manufactured item. The quality of Test and Measurement equipment plays a very important role in a power substation. It helps us in ascertaining the proper aging of any electrical asset while in service, be it a transformer or a cable or a switchgear. “Engineers posted in various substations are now exposed to the best O&M practices used across the globe and are also aware of the latest products available in the market. Therefore, to ensure the quality and efficiency of their power systems, they look for testing instruments that are accurate, reliable, and yield consistent test results. “ said Imteyaz Siddiqui, regional area manager, ISA.

It is conducted on each product manufactured to confirm proper manufacturing of each and every units. This test is essential to be performed on each unit before dispatching the product to site. These tests are intended to check the quality of the individual test unit.
