1. GENERAL The G series P.F.C. equipment is suitable for the centralized P.F. regulation of industrial loads. It may be installed to completely eliminate charges made by Electricity Authorities for any reactive energy used, to reduce the losses for the Joule effect and the voltage losses on the conductors, to take advantage of electrical machines and existing power lines. The P.F.C. equipment uses electronic P.F. Regulator, designed and manufactured by Comar, which controls the value of cosϕ. The extensive range of this equipment makes it suitable for P.F. correction of a wide range of...

Qualified technicians, according to this instruction manual, must carry out the installation. The manufacturer cannot be considered liable for damages consequent to the wrong installation. a) Open the door and connect the automatic P.F.C. equipment to the mains. Cable shall be dimensioned according to the table provided below. Protect the feeding line of the P.F. Regulator with switch fuses or automatic MCCB. b) The three terminals of the main switch are marked with letters R(L1)-S(L2)-T(L3). The phase connected to the terminal marked with letter R (L1) is the one to which the C.T. has to...

enclosed brochure Recommendation for the safe use of static capacitors, banks and equipment for power-factor correction ). CAPACITORS: manufactured according to the more recent reference standards CEI EN 60831-1 60831-2 (IEC 831-1 831-2); they are fitted with overpressure disconnector and discharge resistor, approved by IMQ. The capacitors are impregnated by biodegradable oil or by resin ( Dry type ). The optimal temperature range to work without any problem is: MINIMUM TEMP.: -25¡C MAXIMUM TEMP.: +50¡C (max. daily) MEDIUM TEMP.: +40¡C (daily average) MEDIUM TEMP.: +30¡C (yearly average)...

MHD ANALYSER - Meter of Harmonics Distortion M eter of Harmonics Distortion When the MHD is turned on the THD(I)% value and the reset mode are shown. Through the buttons ↑ and ↓ it is possible to view sequentially the value of current D(I)% related to every odd harmonic. By pressing the ↑ button together for three seconds, automatic scrolling of the measurements is achieved (every 7 seconds). SETTINGS Setup Reset The set-up contains four parameters: Rated frequency (50 or 60Hz) Threshold of alarm (10, 25, 35, 40, 50, 60, 75, 100, 150, 200%) Reset modes (MAN, AUTO1, AUTO2) Type of connection...

Maximum current protection PA6-R The PA6-R card has specially designed to protect banks of capacitors from over-currents. As it is known, the current absorbed by the capacitors may exceed the rated value in various instances, including: Increases in main voltage Conditions of antiresonance between the capacitors and The last instance in the most dangerous, as the resulting current may exceed the rated level significantly, thus causing the capacitors to age precociously and leading to irreparable damages to both the capacitors and the line. The function of the PA6-R protection is to switch...

7. INSTRUCTIONS, WARRANTY AND LIABILITY GENERAL INSTRUCTION Recommendations of the manufacturers • Read the instructions in this handbook because they furnish important indications about the safety of installation, use and maintenance. Take carefully this handbook for any information. • Check the integrity of the equipment after unpacking it. In case of doubt, don t use the P.F. Corrector and ask for skilled staff. N.B. If the equipment has fallen down or has been violently, shaken during shipping, it could suffer internal damages which may be dangerous. • Before connect the equipment,...
