Examples of jobs on Three Phase Power|
|Two Phase Electrical Power began very early for large buildings. Originally known as a polyphase alternating current
electric power distribution system. Two circuits were used with four wires, two for each phase. Some early two-phase generators had two complete rotor and field
assemblies, with windings physically offset to provide two-phase power. By the early 1900's, two-phase power was superseded with three phases except for
commercial distribution in center city Philadelphia. PECO Energy has continued the service due to the difficulty in changing the internal electrical systems
inside all the buildings that still depend on it. Contact us for Modifications, Transformers, Converters for Commercial and Industrial.|
We are the "Two Phase Problem Solver"
Two-Phase Electric Service? Ask me about it.
Many properties in the city are stuck with the oldest type of commercial electrical service "two-phase".
This was the norm 100 years ago, many properties are permanently wired for it so it remains active today.
Ask us about ways to deal with your electrical service limitations. We can provide the circuits required for any new equipment.
Call us about aerial or underground utility connections for service entrance power panels. Hard to find circuit breakers, motors and control panels.
Two-Phase electrical service experts for elevator motors and special equipment. High reach bucket truck service. Our Electrical Service Upgrades Include:
200 amp, 400 amp, 800 amp to 2000 amp.
Voltages - 4160v, 480v., 277v. 208v. 120v.

The ratio of the peak voltages and peak currents in the primary and secondary windings are determined by the
ratio of the number of turns in the primary and secondary windings. The latter ratio is usually called the turn ratio of the transformer.
If the secondary winding contains less turns than the primary winding, the peak voltage in the secondary circuit is less than that of the primary circuit.
Keeping the cost down! Repairs to fused disconnects, magnetic motor starters, electromagnetically operated contacts, push buttons for equipment - start and stop.
Research for connected motor load and control circuits with momentary contact devices.
Connections to the coil of the magnetic motor starter performs this start and stop function. A 3-pole full-voltage magnetic motor starter is made up of the
following components: a set of stationary contacts, a set of movable contacts, pressure springs, a solenoid coil, a stationary electromagnet,
a set of magnetic shading coils, and the moving armature.

A "Phase Converter" is the most cost effective way to produce three phase power from any electrical service.
Basically it's an electrical motor / generator. Single phase input. Three phase output.
|Center City Philadelphia - What to do when 3 Phase is needed? The answer - Three Phase Converters.
You can generate 3 phase power with a Rotary Phase Converter.|
Other Notes: A four-wire system with symmetrical voltages between phase and neutral is obtained when the neutral is connected to the "common star point" of an all
supply windings. All three phases will have the same magnitude of voltages to the neutral in such a system. Other non-symmetrical systems have been used.
In a high-leg delta system, one winding of a delta transformer feeding the system is center-tapped. This setup produces three voltages.
If the voltage between center tap and the two adjacent phases is 100%, the voltage across any two phases is 200% and neutral to "high leg".
Most 3-wire distribution systems need one less conductor and help redistribute unbalanced loading during transformation going back to
the generation source. The 4-wire wye neutral wire is for more voltage selections. Faults on one phase to ground will cause a protection event
locally and not involve other phases or other connected equipment.
