LKV Triphase Power Saver

Energy management systems

LKV’s optimizers help to reduce the electricity bill of professionals.

LKV boxes increase energy efficiency by acting mainly on the power factor and reducing Joule losses. To do this, the box includes a capacitor bank and harmonic filters managed in real time by a computer.

For subscriptions 42 kVA to 240 kVA, the LKV box will make it possible to reduce the power subscribed at the time of subscription (apparent power) or to avoid apparent power overruns (which are overcharged) by improving the power factor. Moreover it will improve the harmonic distortion rate and reduce the thermal effects on transformers due to a bad K factor (ANSI / IEEE C57.110 standard).
Harmonic distortions are generated by switched-mode power supplies (televisions, computers…) which pollute the electrical network.

The installation of the box is easy and must be done at the exit of a TGBT. The boxes are guaranteed for 5 years. LCD indicators permanently display voltage, current, power factor and apparent power saving.

The average energy saving can be estimated at 8% for installations with resistive (lamps, heating, cooking…), inductive (motor equipment) and capacitive (equipment with capacitors) loads. This figure can reach 20% in the case of purely inductive loads.

The LKV set is easy to install, the results are immediate.

A few theoretical recalls

The current delivered to a user is an alternating (sinusoidal) current.
To simplify, this current has three components:
– the apparent power S (in Volt Ampere)
– the reactive power Q (in Volt Reactive Ampere)
– the active power P (in Watts).
