Lifasa

LIFASA capacitors are manufactured using the most advanced technologies, coming from an in depth knowledge of the manufacturing process and also from very strict laboratory and R+D tests. The enormous experience in installations, acquired over many years, allow us to incorporate in the new design the necessary characteristics to optimize the use of the product.

POLT Three-Phase Cylindrical Capacitor

Self-healing capacitors with low losses metalized polypropylene dielectric without liquid impregnants. They have an overpressure disconnection system that disconnects the capacitor in case of any internal failure. Capacitors in cylindrical aluminum cans, provided with a M12 stud for fixing and earthling.
Connection is made by a double 6.35 mm Faston terminal. Optionally, provided with discharge resistors for external connection. These capacitors are especially suitable for the individual compensation of small inductive loads and the construction of small capacitor banks. They have discharge resistors externally fitted.

POLB Three-Phase Cylindrical Capacitor

Self-healing capacitors with low losses metallized polypropylene dielectric without liquid impregnates. They have an overpressure disconnection system that disconnects the capacitor in case of any internal failure.
Capacitors in cylindrical aluminum cans, provided with a M12 stud for fixing and earthling. Connection is made by a terminal block with clamp type terminals. They have discharge resistors integrated in the terminal block.
These capacitors are especially suitable for the individual compensation of small inductive loads and the construction of small capacitor banks.

Reactive power controllers MCE ADV and PFCL are designed to measure the reactive power of an installation and to give the necessary instructions for connecting and disconnecting capacitors in order to maintain the desired cos φ .
All the controllers are commanded by a microprocessor that ensures an uniform ageing of contactors and capacitors by using a circular connection sequence that takes into account the time that each capacitor has been switched on. Power factor value to be reached can be adjusted in a continuous way, between 0.85 inductive and 0.95 capacitive.

MCE ADV Standard Controller

Power factor controllers MCE-6 ADV (6 steps) and MCE-12 ADV (12 steps) measure the cos φ of a supply system and control the automatic connection and disconnection of compensation capacitors, according to desired cos φ.

PFCL ELITE Advanced Controller

PFCL Elite controller has a built in power analyzer allowing the measurement of main electrical parameters (voltage, current, harmonics, active and reactive power, apparent power, etc.). The device gives a detailed information on both, voltage and current harmonic components. PFCL Elite controller measures also ambient temperature and keeps a record of maximum and minimum values of all measured parameters.

Protection filters are used, in supply networks having a high level of harmonic distortion, when the final objective is reactive power compensation at the fundamental frequency.
Their purpose is to avoid that harmonic currents overload the capacitors by diverting them to the mains. Protection filters are made by connecting reactors in series with capacitors, in such a way that the tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonic, which is usually the 5th order harmonic. In this the filter has a high inductive impedance for all the harmonic frequencies.

INA/INR REACTOR FOR STANDARD CAPACITOR BANK

INA/INR reactors are designed to work in supply systems with a high level of harmonic distortion in such a way that they allow a safe and reliable service of the power factor correction equipments. Reactors are connected in series with power capacitors, forming a resonant circuit conveniently detuned, so that, the whole unit has an inductive impedance at the frequencies of all harmonics in the installation. These reactors are specially designed to work in series with FMLF capacitors.
