Abstract

In an effort to meet customer needs on supplying electricity in the industrial era 5.0, it needs to have good services which keep growing up and be innovative. One of them is running a premium service which guarantees better quality of service than that of the regular. This research will discuss all of the obstacles that can disrupt the continuity of electricity supply to the customer with premium services, starting from the disruptions at the supply side until at the installation owned by the customer. From the analysis result, ATS (Automatic Transfer Switch) failed several times on working so that caused a black out at the customer side which it should be avoided. Therefore, it is necessary to make some adjustments on setting and wiring to some problems which may arise so that the potential disruption of the ATS or equipment failure can be suppressed. This research aims to minimize and even eliminate ATS performance failures due to system disturbances by implementing rewiring, adding a permissive interlocking system and adding a PLC with a time delay setting.

Abstract

This analysis will discuss how to handle vibrations in the Turbine Rotor. The measuring instrument used is Vibration Analysis test with Prov. 2140 type which measured amplitude, time and frequency domain of vibration signal. The results obtained in this study, firstly, the measurement vibration of rotor at PT PJB Gresik found the highest amplitude of vibration was 59,6 μm at 3000 rpm. In this condition, the rotor is in very good condition as per standard vibration in ISO 7919-2 stated 80 μm at 3000 rpm. However in the next measurement, there is an dramatically increase of amplitude in each vibration measurement. The top amplitude of vibration reached at 115 μm at 3000 rpm and shown a symtom of damage on the rotor as a result of vibration. In solving the problem this time we use the method Root couse analysis (RCA). The results of this research found that there was a short turn to turn on the rotor windings and the closed slot liner holes that caused electric vibrations and needed to be repaired to eliminate vibration disturbances. After repairing the vibration, it decreased which initially 115 μm to 33.5 μm at 3000 Rpm, it is still on the range of the permitted safe zone of ISO standard 7919−2.
