Reactive Power Compensation Units (UKM)

UKM-0,4 (Ukr. УКМ-0,4) reactive power compensation units are capacitor units for maintaining a set power factor (cos φ) in 0,4 kV (400 V), 50 Hz distribution networks. They are used to compensate the reactive power of loads with an inductive character (asynchronous motors, welding equipment, transformers, lighting ballasts) — sufficient for most facilities. This reduces reactive energy consumption and the associated charges, and relieves the load on the network and power transformers.

The unit is fitted with capacitors, which form the basis of compensation. Reactors (anti-resonance / filter types) are added only when needed — for facilities with a capacitive load character or where there is a risk of resonance and an elevated level of higher harmonics. A microprocessor-based controller automatically switches stages on and off according to the actual load, keeping cos φ close to the set value without the involvement of on-duty personnel. LK Energy Group (a switchgear equipment manufacturer, Odesa, since 2005) manufactures UKM units to the parameters of a specific facility; the standard configuration uses ETI components (less often — Vektor), depending on availability and project requirements.

Each unit is designed for the actual reactive profile of the facility: power, number and step of regulation stages, and design are determined per the project/specification. By eliminating overpayment for reactive energy, the unit reduces electricity costs; the payback period depends on the tariff, the cos φ level, and the operating mode, and is determined by calculation for the specific facility.

UKM-0.4 is a reactive power compensation unit for 400 V, 50 Hz networks. In most cases, compensation of inductive load is performed with capacitor banks (ETI components, less often Vector); for capacitive load and resonance protection, reactors are added. The regulator automatically switches steps to maintain the target cos φ without attendant staff. Range 25–600 kvar, design built to project/specification. LK Energy Group is a switchgear manufacturer from Odesa (since 2005): we design and manufacture the unit for your load, with documentation per TU U 27.1-40132794-003:2016 (Ukrainian technical specifications).
