All the types of electrical noises, predominantly common mode noises can be eliminated by Ultra Isolation Transformers. Since it isolates primary and secondary or separates neutral to ground bond on the secondary side, can be used to create separately derived source to combat current loops. The Ultra Isolation Transformers are available in different levels of noise attenuation capabilities. The most commonly used are 100 & 120 dB. The coupling capacitance between primary and secondary is direct 1:1 relationship with dB levels. Some of the graphs herewith indicate different types of electrical noises observed in typical Engineering Industries & successfully eliminated.

Corrects Voltage Fluctuations before it damages your Hi-tech Machines. The purpose of voltage stabilizer is to receive a fluctuating AC voltage of low or high amplitude & deliver an almost constant voltage, at the output. The voltage variations, which have become a common phenomenon in power supply systems, cause havoc in modern advanced electronic equipments. The voltage stabilizers are meant to take care of this problem. They avoid breakdown, ensure longer life of the equipments & save in energy during high incoming voltages.

We offer powercon the two-in-one for voltage and spikes correction. large amount of cnc breakdowns are attributed to fluctuations in voltage and various types of electrical noises like spikes, surges, h.f. Noises, ground noises, etc. electrical noises are generated due to switching action of breakers, heavy, machinery, capacitor switchings, induction hardening, cranes, welding etc. The use of invertors, dc drives, smps, further pollutes the electrical environment, causing severe power quality disturbances to various cnc machines, installed in the plant. Advanced cnc machines demand stringent standards of power quality for their smooth and trouble-free operations. neel powercon eliminates major electrical disturbances and provides clean power to your cnc machines.

True on-line double conversion micro-controller based UPS system for high end servers, workstations, CADCAM...sensitive to AC power irregularities and blackout. The high switching frequency of the UPS enables fast response to dynamic loads like CNCs, textile and printing equipment, glass processing, medical equipments..., resulting in good transient response for non-linear loads. The UPS is designed to support advanced electronic equipments with high crest factor demand and provides unmatched performance.

K-factor is defined as a ratio between the additional losses due to harmonics and the eddy current losses at 50Hz. K-Factor is defined as a ratio between the additional losses due to harmonics and the eddy current losses at 50Hz. It is used to evaluate transformers for nonlinear loads. Transformers with a rated K-factor of 4, 7, 13, 20 and 30 are available. The ANSIIEEEE C57.110 has derived a system of weighing how much harmonic load currents a transformer can handle without exceeding its maximum temperature rise level. A K factor of 1 indicates no harmonics, while a K factor of 50 is the harshest harmonic environment possible. Typically a K Factor of 13 is sufficient for most applications. K factor must be determined to calculate the right size transformer that is needed.

Power problems due to improper grounding: Good grounding of electrical systems is most important. Most power quality problems in electrical systems are due to wiring & grounding problems. A properly grounded electrical system exists when a grounding conductor is connected to the neutral conductor only at the input transformers. From this point on, the neutral &ground conductors should not be bonded together. With advanced equipment like computers, CNC machines & other digitally controlled equipment, the quality of ground & ground currents are of prime importance. Harmonics can also cause large amount of ground currents. It can cause loss of memory, data corruptions or at times system failure. Hence, ensure that the ground currents are within permissible limits, under all dynamic conditions of load.
