“…Medium voltage cubicles are usually found in substations or distribution substations [12]. Cubicles are often defined as switching equipment and combinations thereof, equipped with measurement, control and protection equipment, while according to [13] Mediumvoltage cubicle is an electrical component that is connected to a 20kV medium-voltage power grid.…”

Cubicle is an electrical device that functions as a breaker, protector, connector, controller, and divider of the power system electricity from a power source and reduce sparks when connecting. One of the problems that occur in medium voltage cubicles is the presence of corona. Corona phenomena at cubicle terminations can trigger disturbances such as a decrease in insulation quality, power loss and a significant increase in harmonic distortion. Based on previous research, the solution to minimize the occurrence of corona is to optimize the temperature and humidity of the cubicle. Many of the previous studies examined the control of cubicle temperature and humidity using fans and heaters, but the temperature and humidity had not yet reached a stable and optimal point. In this study, raised a problem regarding the optimization of temperature and humidity in cubicles using the fuzzy method to stabilize the performance of medium voltage cells. In this study, it was found that the fuzzy method in this prototype was able to stabilize the panel humidity at 55% RH and stabilize the panel room temperature at 31.5 o C. Thus, it is hoped that a stable and optimal temperature and humidity can minimize the occurrence of corona. The use of HMI/SCADA based applications can facilitate the ability of the user (operator) to monitor several available parameters and manually control the operation of the panel (on/off).

“…A Busbar fault at an Electrical Substation affects a lot of equipment and can cause tripping on the busbar which will break the circuit as a protection mechanism [2]. The Busbar connects all the bays at an Electrical Substation [3], when there is a busbar fault all the bays and alarms trip at the same time. Indications are sent to the RTU, this creates a huge traffic within a short space of time, at the same time controls are sent to the D. Njova and P.

During Substation maintenance a bay is taken out of service, tested and during testing traffic is generated on the Substation Communication Network (SCN) in a power utility. A model of a Substation Communication Network that is using the International Electrotechnical Commission (IEC) 61850 protocol has been modeled in Optimized Network Engineering Tool (OPNET). IEC 61850 is a protocol that can be used in a power utility to provide interoperability between different vendors of Intelligent Electronic Devices (IED's). Most of the IED's sold by manufacturers for power utility networks support IEC 61850 protocol. The model has three scenarios and they are normal operation of a Substation, maintenance in a Substation and Buszone operation at a Substation. In all the scenarios packet end to end delay of GOOSE, GSSE, SV and MMS messages are monitored. The throughput from the IED under maintenance and the throughput at the Substation RTU end is monitored in the Model. The design of the Substation Communication Network using IEC 61850 will assist when trying to predict the behavior of the network with regards to this specific protocol during maintenance and when there are faults in the communication network or IED's.
