"Circle Electric Co" manufactures Power Distribution system, consisting of a Main Distribution Board (MDB), Sub Main Distribution Boards (SMDBs) and Final Distribution Boards, by which the electrical energy is transmitted via branches to reach the exact end user.

An MDB is a panel or enclosure that houses the fuses, circuit breakers and ground leakage protection units where the electrical energy, which is used to distribute electrical power to numerous individual circuits or consumer points, is taken in from the transformer or an upstream panel. An MDB typically has a single or multiple incoming power sources and includes main circuit breakers and residual current or earth leakage protection devices. A MDB is comprised of a free standing enclosure, a bus bar system, MCCB’s, metering and support equipments and required current transformers. Panels are assembled in a systematic manner such as incomer section and outgoing section.

The MDB then feeds SDBs, which is installed generally at the point where a large distribution cable terminates and several smaller sub-circuits start. These are the switchboards that although similar construction, are larger than a final distribution board circuit. The boards are installed midway through the power distribution system, at the point in a large distribution cable ends, and several smaller starting sub-circuits. 

"Circle Electric Co" manufacture all kind of HT VCB panels for 11KV/33KV system. Our array of precision engineered Vacuum Circuit Breaker (VCB) Indoor Panels are manual or motor operated. We give our most importance on the quality and safety factors during manufacturing the VCB panels.

The 11KV HT  Panel with LBS is suitable for indoor & outdoor applications. The Switching Panel consists of a Load Break Switch  that can be used for Switching ON & OFF of  the Transformer. The HRC Fuses used conforms to International Standards.  The protection / Tripping System is Implemented through fuses blown. 11 KV CT, PT are used for measuring as well as protecting the system. 

"Circle Electric Co" 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. Necessary indications  and measuring equipment for current, Voltage, Power (optional) are built in so that the panel operator can easily monitor the usage. All the bus-bars/live parts  are well insulated to avoid any kinds of accident.

Power Factor of the system is degraded due to inductive load of different industries and big apartments. Power-Sonic 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.
