Description
Each phase is regulated independently, so the imbalance between phases, usual for factory grids with powerful single-phase consumers, is evened out at the output. A digital microprocessor control unit shows the parameters on an LCD display. Grids of 380–415 V, 190–240 V and 440–600 V are supported. Efficiency is at least 95 %, but at the level of thousands of kVA even a few percent of losses give noticeable heat that must be removed by ventilation. Built-in suppression protects the input against surges. A manual bypass takes the stabiliser out for maintenance without stopping the site, and the automatic one operates without an operator.
How to choose
The power is selected from the substation transformer or the main supply breaker, and among 17 ratings there is usually a close one. Below 450 kVA the ESR-3P-T1F for 6–400 kVA with a wider ±50 % input range is more appropriate. For single-phase lines there is the ESR for 3–100 kVA.

FAQ
What is the power of the ESR-3P-T2F/T3F stabilisers?
From 450 to 3125 kVA, with 17 ratings in the series, so a suitable model can be found for most substation transformers.
Does the ESR-3P-T2F/T3F even out phase imbalance?
Yes, regulation is independent per phase, so each phase is brought to the nominal value separately.
What is the input voltage range of the T2F/T3F series?
Grid deviation of up to ±40 %. The smaller ESR-3P-T1F series has a wider range, up to ±50 %.
How is the stabiliser maintained without disconnecting the load?
Through the manual bypass the load is transferred directly to the grid and the stabiliser is taken out for repair. The automatic bypass operates by itself in case of a fault.
How is the operation of the ESR-3P-T2F/T3F monitored?
Control is digital and microprocessor-based, and the duty staff see the phase voltages and the unit status on the LCD display.
