Solutions & Application

Solutions

There is a trend to adopt the techniques of 'Predictive' Maintenance. Need to adjust the maintenance activity rather than relying on fixed maintenance intervals. The hard-pressed utility or plant maintenance engineer needs to focus limited time and money into the areas that are most critical and most at risk.

Insulation tester Application

A major cause of equipment failure is breakdown of the insulation. There is a range of diagnostic techniques that can be applied to monitor insulation condition in order to take timely maintenance action.

The traditional insulation resistance test is the simplest way to gain an overall indication of the condition of the insulation. Although the Insulation Resistance test can be applied as a simple Go/No Go test, it can also be used to give more extensive diagnostic information. The Power Generation and transmission and distribution industries have for years been the most widespread users of diagnostic insulation tests, such as the Polarization Index (PI test).

The commonest voltages applied for non-destructive DC Insulation tests are 2.5 and 5kV.

Insulation test is one of the mandatory test in preventive or shutdown maintenance, It has wide range of Application in Power industry, refiners, motor manufacturing, transformer manufacturing, generator manufacturing, etc
