The standard instruction for construction of 33/11 kV substation is given in REC standards which specifies the layout along with the switchgear. The standard layout guides for the general arrangement of the equipments, structures, bus-bars etc. of outdoor substations. The general specifications of a substation cover the details of the major equipments and other items to be supplied.

Starting method significantly affects the starting current, torque, mechanical stress and hence the life of an induction motor. The soft starter electronically controls the starting torque and current of an Induction motor. Their field of application includes HVAC fans and pumps, industrial fans, pumps, conveyors and other processing equipments etc. Soft starters can be used with both 3-phase and 1-phase induction motors. The following material is intended to acquaint the reader with the theory and operation of solid state soft starter and motor controller.

An electrical engineer and electrician must be familiar with a variety of test and measurement instruments. They need to know how to use these instruments in a safe and proper way under different working conditions. It is important to use the right tools and instruments when working with electricity. Appropriate equipments can make a hard task easy and at the same time wrong selection can make an easy job difficult and dangerous.

This article looks at the most common type of meter available with an electrical engineer or electrician; i.e. the Multi-meter.

In the power transmission line when the line conductors are asymmetrically spaced i.e. not equally spaced, the inductance of each phase is different causing voltage drops of different magnitudes in the three phases even if the system is operating under balanced condition (load currents are balanced in the three phases). Also the magnetic field external to the conductors is not zero thereby inducing voltages in adjacent communication lines and causing what is known as “telecommunication interference”. This can be overcome by the interchange of conductor positions at regular intervals along the route and this practice is known as “transposition of conductors”.

A clamp meter is a more versatile instrument that combines a clamp-on ammeter with a multi-meter. It is usually capable of measuring alternating current, AC/DC voltage, and resistance. Many of these meters are able to test the capacitors, measure frequency, temperature, continuity etc.

Modern power cables come in a variety of sizes, materials and types, each particularly adapted to its use. These cables comprise of conductors, insulation, inner sheath, armour and outer sheath.

The construction and materials of cables are determined by three main factors..

The electrical and electronic equipments and systems used in any power system network are designed in such a way that they are safe during normal operation, but in case of mal-operation or faults they can be very dangerous.
This article is supposed to throw some light on safety aspects, and to grab the attention of our young engineers and technicians.

Roof top solar PV systems are going to witness appreciable capacity expansion particularly on the residential and commercial buildings in India and can be seen as a significant business opportunity. The feeding of excess energy, produced by the solar PV system, to the grid or the drawal from the grid in case of insufficient solar power generation is through a net metering arrangement.
