Best Isolation Transformers Manufacturers & Suppliers

Isolation-Transformer-3

GM Electrical Systems are currently supplying a series of 1:1(Step Down or Step Up) ratio isolation transformers for a major rail electrification project in the India. Single Phase Transformer and Three Phase Transformer are being supplied in ratings from 25 kVA to 90 kVA. The main purpose of using transformer is to separate traction which is supplied from the mains network. These isolation transformers are installed in outdoor locations depends on IP55 enclosures and these are fabricated from stainless steel with a painted finishing.

Isolation Transformer: 

Most of the isolation transformers are using in railway sectors, there is a regulator need for transformers to meet specific power & installation requirements. which means a non-standard transformer assemblies have to produce on a daily basis. Due to the cost &  time to carry out complete solutions of type tests, widely accepted international compliance with standards can be established by extrapolating from the results and type tests carried out on similar products. For long term commitment, high profile projects requiring large quantities of isolation transformers, specific type testing can be undertaken. However, this does extend time scales, increases cost, which should be factored in from the start of the project.

Specification of Isolation Transformers:

Primary Voltage: 230V, 50 Hz, 1 or 400V, 50Hz, 3

Secondary voltage: 230V, 50 Hz, 1 or 400V, 50 Hz, 3

Load Regulation: 3.5 to 7%

Input Voltage(Allowable): + 10%

Mode of Operation: 1: 1 or Step Down or Step Up

Offline UPS supply grid power to electrical & electronic devices during normal power supply. Offline UPS switches to battery power only when power failures and other power problems. As the grid power is by passed to the load during the power system, is called as Offline UPS. UPS used only when we facing power issues is also called as Standby UPS. Apart from bypassing  power to the loading system, a charges is connected to the batteries, as a result it expose the load to electrical noises and surges. This is the reason, they aren’t recommended for any critical electronic devices. When power failures, automatically they switch from grid power to battery power to prevent computers from rebooting.

Online UPS:

Online UPS supplies power to electrical and electronic devices from batteries all the time. Firstly, the UPS converts grid power to charge the batteries & then discharges the batteries to power load. Henceforth, battery power is supplied to the load at all times is known as Online UPS. The grid power is converted from alternating current to direct current to charge the battery and simultaneously a battery power is converted from DC to AC to load the power. Therefore Online UPS is also called as Double Conversion UPS.
