Electrical Insulators and it's types

Image
The electrical insulator  is a device that provides the required insulation between the line conductor and earth. Due to this insulation, leakage current can’t flow from the line conductor to earth. Insulator a material or a device which restrics the flow of free electrons (or charge).  The successful operation of an overhead line depends to a considerable extent upon the proper selection of insulation.  Importance of Electrical Insulators- The insulator work as a Protector or Protective device. Because it provides high resistance. Insulator helps to protect from heat, noise, and electricity. The insulator is used to support the overhead conductor. It is commonly used to insulate the live parts of equipment or conductor from the earth. The live conductor is protected by wrapping the insulation. It helps to protect switchgear, transformers. Properties of Electrical Insulator- The electrical insulator has a high resistivity. Insulator has good mechanical strength for the c...

Type of solar Panel and features

Image
Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat .  Solar panel is actually set of photovoltaic modules, mounted on a structure supporting it. The Benefits of Solar Panels Solar panels make it possible to live off-grid. It is both a clean and a renewable source of energy. Low maintenance cost. Once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! Types of Solar Panels The solar panels can be divided into 4 types, Monocrystalline solar panels Polycrystalline solar panels Passivated Emitter and Rear Contact cells (PERC) solar panels Thin-film solar panels 1- The monocrystalline solar panels  They are also known as the single crystal panels. They are made from pure silicon crystal which is sliced into several wafers forming cells. These wafers ...

Transformer maintenance

Image
Transformers are an expensive and important part of any machinery. So for getting optimal performance and increased product life, it is best to conduct regular maintenance checkups on your transformer. There are basically two types of transformer maintenance. One is done on a regular basis and the other is done at the time of urgency.  If maintenance checkups are done on a routine basis then you may not have to undergo breakdown maintenance and hence save downtime. There are a lot of different types of maintenance checks to be conducted on a power transformer. Here are some of the main transformer maintenance actions that have to be performed: Transformer Maintenance Checks on a Monthly Basis: Oil level in the oil cap must be checked on a monthly basis so that it doesn’t drop below a fixed limit and hence avoid damage due to it. Keep the breathing holes in the silica gel breather clean to ensure proper breathing action at all times. If your electrical transformer has oil filling bu...

Electrical Power Distribution System

Image
Electrical Power distribution  is an essential part of the electrical power system. Distribution system is Electrical System between substation fed by transmission system and the consumer end.  According to nature of current Distribution System is classified in to AC Distribution System DC Distribution System  Electrical energy is generated, transmitted and distributed in the form of alternating current. One important reason for the widespread use of alternating current in preference to direct current is the fact that alternating voltage can be conveniently changed in magnitude by means of a transformer. For certain application DC supply is absolutely necessary. DC supply is necessary where variable speed machinery are used, for electro chemical work also in congested area where storage battery reserves is necessary .  This Single line diagram shows general layout of Distribution System. Distribution system employs Feeders, Distributor and Service mains. Feeder - It...
