Thermographic Analysis

Thermographic Analysis

Inasset is periodically performing thermographic inspections on environment and electromechanical devices, as precautionary measure in order to improve efficiency and to limit costs. Analysis tasks are performed by internal staff with certified and calibrated devices, in compliance with ISO 20000 procedure manual.

Introduction
The main purpose of performing thermographic analyses is to measure and analyze thermic anomalies on electromechanical devices working at maximum load conditions. IR cams are set up to read irradiated frequencies produced by the parts taken into consideration. Following such method and after using dedicated data capture and analysis tools, it is possible to display them visually and determine even the slightest temperature variations of working parts and system components. Correct interpretation of acquired radiometric images is guaranteed by creating thermal charts. Data gathered with this method are later used to perform simulations and to define all possible events associated with surface temperature variations.
Thermographic analysis gives the possibility to perform non-destructive inspections, very effective in quality controls for the abovementioned aspects. Such analytical system is extremely useful for planning and control of production plants. If included in periodic maintenance tasks, it will reduce the frequency of malfunctions in production systems and lead to a logical implementation of resources devoted to maintenance activities.

Systems load check

All analyzed devices are subject to an average load that is 50% lower than related nominal values, detected by using dashboard tools or a current clamp. The analysis covered those electrical devices belonging to medium voltage/low voltage cabin transformation/distribution systems (2 parallel transformers, 800 kvA each), as well as devices and power distribution boards in BT1 and BT2 rooms, currently in service.
Analyzed devices are operating at “MAXIMUM” capacity load with respect to the density of operational devices. Lacking further reference parameters, indirect evaluation of electric system’s load capacity is performed by using maximum values for switches/transformers, assuming a minimum range of 20% precautionary margin (e.g. inter. 630 [A] X 0,80= 504 [A], equal to plant maximum load (100%)).
All low voltage distribution systems are operating in environmental conditions suitable for electromechanical components to work properly. All areas are air-conditioned, with a temperature ranging from 23°C to 25°C.
Analyzed devices are guaranteeing distribution of electricity to technological systems and datacenter’s internal users along with references indicated by InAsset technical staff.
