KWH meter system of Automatic Meter Reading or hereafter will be referred to the kWH meter AMR is a recording system of electric energy meter is done automatically and remotely.Communication data sent by the kWH meter AMR of PT PLN (Persero) Jakarta and Tangerang Distribution using SMS modem which interfacing kWHmeterselectronic withwireless telecommunications networks. kWH meter AMR have features other than noting the energy used, also noting the voltage, electric current, power factor(cos ϕ), and as well as the use of electricity meters in record-keeping more quickly. Thus the PT PLN (Persero) Distribution can perform distribution network management (DNM) that makes it easier in terms of channeling energy into customers and monitoring the electric energy usage by customers. The results of the analysis of kWh meter AMR system can reduce losses caused by abnormalities in the distribution network system. SMS telemetry signal communication with the modem is unstable and often fail withdrawal data. To overcome the problem of the use of the old modem, the modem needs to be replaced with GPRS / LTE user ready. However, the use of power line communication (PLC) as a data transmission network to reduce reliance on mobile telecommunications networks.

High resistance grounding one of the ways ptotection generator for the single phase earth fault. High resistance grounding utilizes a distribution transformer with a primary voltage rating greater than or equal to the line to neutral voltage rating of the generator. The distribution transformer should have sufficient overvoltage capability so that it does not saturate on single line to ground faults with the generator operated at 105% of rated voltage. The power dissipated in resistor is approximately equal to the reactive volt-amperes of the zero sequence capasitive reactance of the stator windings. For High resistance grounding to be effective, the size of resistor must be carefully selected for each system. IEEE Standard C37.101 provides a detailed example of how to determine the size of the ground resistor to meet the requirements cited above, as well as calculate the resulting ground currents and voltages.

In urban areas the use of underground cables is growing rapily in recent. Cable line are used to distribute electrical energy is called high voltage cable line. When a ground fault occurs in a power network, a ground fault current flow towards the sources through the earth and the other flow through mettalic sheath of the cable. For safety in substation reduction factor must be small. In this paper present the method for calculate reduction factor value at three single core cable. This method can give the value of reduction factor for different distance and different ground fault locations,happened between source substation and suplied substation.
