Annual testing, inspection and maintenance is required under the current BS EN 62305-2006 & the superseded BS6651-1999. Testing and associated maintenance ensures a lightning protection system is functioning correctly. We provide the following services in this field:  The Electricity at Work Regulations 1989 state that lightning protection systems should be tested annually.All our engineers are qualified to CITB level 2 minimum   Detailed log books issued on completion of all tests and inspections (including up-to-date calibration certificates)   CAD drawings can be supplied at no additional cost, using existing data or Google Earth technology  All documents are supplied electronically in PDF format.

Why Our Service.. ?  Lightning Arrester is the device used to protect the insulation and conductors from damaging effects of lightning on electrical power systems and telecommunication. Typical Lightning Arrester has a high-voltage terminal and a ground terminal. When a lightning surge travels along the power line to the Arrester, electricity from the surge diverted through the Arrester to the earth.If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilo Volts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices. Lightning-produces extreme voltage fastens in incoming power lines would damage electrical home appliances that’s why it is essential to the principle of Lightning Arrester.

The power loss can check by several methods given below:

Using a voltage signal as reference

 Compensating the capacitive element by using a voltage signal.

 Capacitive compensation by combining the leakage current of the three phases.

 Third order harmonic analysis.

 Direct determination of the power losses.

 Third order harmonic analysis with compensation for harmonics in the voltage.

 Protect all electrical system and human being.
