Substation is one of the major part of electrical distribution system to distribute
the power from generation to user end. SYSTECH try to give proper solution to
client for every step of Substation from design to commissioning as per requirement. Proper design can ensure the risk free use of power as well as longer life of substation equipment’s. SYSTECH is “developing capability to execute high
voltage substations i.e. GIS or AIS up to the highest voltage level collaboration by international expert on relevant field”.

Transformers

A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.

Systech Engineering Ltd. supply and maintain various types of Distribution & Auto transformer for all over Bangladesh.

HT Switchgear

In an electric power system, HT switchgear is the combination of electrical disconnect switches, fuses or circuit breakers both VCB & LBS used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.

Systech manufacture, supply and maintenance of HT Switchgear for rated voltages of 6.6 to 36 kV, with rated short-circuit breaking capacities from 25 to 40 kA.

L&T Switchgear

Systech manufactures low voltage switchgear (hereafter called LT Panel) which is applied for power control and distribution systems of AC 50Hz, rated working voltage up to 500V. It’s mainly used in indoor/out door substation, power station, industrial enterprise, Commercial/Residential Buildings for power distribution and can be used to control, protect and inspect the circuit. LT switchgears consists of Main Incoming Circuit Breaker (MCCB/ACB) as per capacity of the Transformer, Rated Bus-bars, Out going Circuit Breakers (ACB/MCCB/MCB) in order to control/switch the power required in different machines/sections/purpose.

PFI Plant

Power Factor of the system is degraded due to inductive load of different industries and big apartments. Systech manufactures PFI (Power Factor Improvement) Plant for improving the degraded Power Factor of the system. We have microprocessor based PFC (Power Factor Correction) relay up to 24 stages. The Capacitors we use are of different ratings (2.5, 5, 10, 20, 25, 50 KVAR…. etc) and corresponding Magnetic Contactor for suitable stepping of the Capacitor bank. Sometimes we also use detuned Reactor with the Capacitors for harmonic filtration of the system. We must follow international standard and testing method to ensure qulity, service and life of the equipment.

CT, PT

CT:PT Combined unit are also called metering units. These units can be offered as Dry Type or Oil Immersed and are generally pole mounted. The units are available in three phase three wire or three phase four wire system. CT: PT unit used for single or double metering with trivector meter and energy meter.

Current transformers are used for metering and measurement purposes. High line current can be stepped down for measuring devices and relays. Systech is authorized value added partner of TS Transformer & Vicar Electricals.

Auto Circuit Recloser

In electric power distribution, automatic circuit reclosers (ACRs) are a class of switchgear which is designed for use on overhead electricity distribution networks to detect and interrupt momentary faults. Also known as reclosers or autoreclosers, ACRs are essentially high voltage rated circuit breakers with integrated current and voltage sensors and a protection relay, optimized for use as an overhead network distribution protection asset. Commercial ACRs are governed by the ANSI/IEEE C37.60, IEC 62271-111 and IEC 62271-200 standards. The three major classes of operating voltage are 15.5 kV, 27 kV and 38 kV.

Systech is value-added partner of Rockwell & Antec brand ACR.
