PhaseCap Energy Plus (Resin)
Power capacitor, MKK series (B25675C), semi-dry biodegradable resin · EPCOS AG / TDK Electronics
PhaseCap Energy Plus (Resin) is the premium range in the EPCOS / TDK Electronics power factor correction programme. The winding is metallized polypropylene film in MKK technology — wavy cut with a heavy edge — impregnated with a sustainable semi-dry biodegradable soft resin and sealed into an extruded round aluminium can, three-phase and delta-connected. Two safety principles work together: the film is self-healing, so a local dielectric breakdown clears itself instead of shorting the capacitor, and a three-phase overpressure disconnector takes the unit off the network at the end of its life before the can can rupture. What sets the resin range apart is its duty capability — an expected service life of up to 240 000 hours, an inrush current withstand of up to 500 × IN and up to 15 000 switching operations a year — which is what a compensation panel that switches many times a day actually needs. The range covers 230 to 1000 V and 5.0 to 60.0 kvar across four terminal types, so the same series serves a small fixed motor compensation and the detuned steps of a large automatic bank.

Applications
- Low Voltage Reactive Power Compensation SolutionsIn industrial and commercial facilities the reactive power balance can be upset both by inductive loads such as motors and transformers and by loads with a capacitive effect such as UPS systems, drives and long cable runs. This can disturb the reactive power balance, move the power factor away from the desired level, draw unnecessary current from the network, increase losses and incur reactive energy charges. Low voltage compensation systems hold the power factor at the desired level by providing compensation matched to the facility's inductive or capacitive reactive power demand. Where load changes are rapid, thyristor-switched systems are used to respond quickly to reactive power variation. In facilities where harmonics are present, compensation systems with harmonic filter reactors are applied to keep the capacitors from entering resonance with the network. A correctly engineered compensation system helps to avoid reactive energy charges, to use transformer and cable capacity more effectively, to reduce electrical losses and to improve system performance.
- Medium Voltage Reactive Power Compensation SolutionsMedium voltage compensation systems hold the power factor at the desired level in high-power industrial facilities by supplying the reactive power that inductive loads require within the plant itself. This reduces the reactive power drawn from the network, lowers electrical losses and makes more efficient use of existing system capacity. MV compensation systems can use fixed or automatically stepped capacitor banks according to the needs of the facility. Switching is carried out by vacuum contactors or circuit breakers, and the system is operated safely with appropriate protection and control equipment. Because every facility has a different network structure, load characteristic and reactive power demand, MV compensation systems are engineered specifically for the site rather than supplied as a standard solution. Capacitor rating, step structure, switching devices, the protection system and, where required, series reactors are determined from the measurement and engineering work carried out, producing a compensation system suited to the facility's operating conditions.
