In distributing electrical energy to customers, required a reliable power system. Disturbances in a system of electricity can not be avoided. Generally disruption of the underground channels, prone to disturbance occurs in cable connections (Jointing). Interference that occurs in SKTM in jointing that is existence of partial discharge. From the cable test results of a feeder Debur B 329 to B 162 this is a very bad cable condition. The location of the bad cable is at a distance of 59 to 91 m and 190 to 220 m, with a capacity of 0.272 μF and a frequency of 353.98 Hz. The cable testing to determine the existance on the cable channel and location of the occurance of interference so that it can be done immediately repair or replacement on the cable that has interference.

In this research discusses about PLTS planning studies connected to grid to serve electrical power supply in STT–PLN tower. During this STT–PLN tower get electrical power supply sourced from PLN only where the capacity of power installed 1100 kVA with transformer capacity equal to 1250 kVA. The distribution of electrical power to the STT–PLN tower is obtained from Tolimo feeder which is connected directly to Duri Kosambi 192 Baru substation. So for that in this research made a planning of distribution of electrical power distribution with PLTS – Grid systems where PLTS system serve the use of electricity load from 08.00 WIB – 17.00 WIB, the rest only relies on electricity source from PLN. With PLTS – Grid system, the use of batteries can be eliminated. The electrical loads connected to the PLTS system and grid use the same energy as those supplied by the PLTS for a certain period of time. In this case, the grid becomes a storage or lender temporary for the fulfillment of electrical power demand. So with the application of this concept we only spend the investment cost of the PLTS system without batteries and the cost of leasing the network in the PLTS – Grid system.

The Power Distribution System is basically a process for delivering electricity from a 150 kV power transmission system to a consumer, either 20 kV consumer or a 380/220 V consumer. The more complex distribution system of the network is the Low Voltage distribution system (380 / 220V), because the network of low voltage distribution system has a very wide network coverage. This often causes the Low Voltage Distribution system to be unbalanced, since household customers generally utilize single phase power. The effects of an unbalanced low voltage distribution system will affect many things, such as : the transformer's performance, excess heat in the overload phase, the current flowing in the neutral wire, the end-tension drop in the overload load network. And ultimately the quality of electricity at the consumer level decreases. With this load imbalance, the workable solution is to balance the load on the transformer. The measurements of Jurusan B after load balancing are the R-phase 106 Ampere, the S-phase 108 Ampere, and the T-phase 107 Ampere. The load unbalance value drops to 1% after a load balancing effort, this value is far below the maximum imbalance criterion of 10%.

Measuring tool can be defined as a tool that can know the value of used in a unit based on the level of accuracy. Household electric current measuring devices are often used now still use analog systems are slightly complicated in terms of reading the value of the output, it's because the viewer uses a needle that points at a certain scale. Besides the current measuring device ac and dc electricity in the market generally, very rarely menggunkana microcontroller. Based on that the authors designed an ac and dc based arduino uno power meter is using the current sensor acs 712 30 amps. This tool takes the working principle of the amperemeter, ie the principle of magnetic force (lorentz style). It's just different from the multimeter that uses a probe as a current conductor medium, this tool uses the terminals as a medium of conductor current. This tool can be used to measure all household electronic appliances or offices either AC or DC current.
