International Resource News-February 10, 2016--Gridco Systems launches Gridco Systems Power Regulating Transformer (PRT)
Gridco Systems, a company involved in agile grid infrastructure solutions, has introduced a new product, the Gridco Systems Power Regulating Transformer (PRT).
The Figure 4.c indicates higher voltage regulating transformer with the optimization proposed, this was expected because the windings are larger, and resulting in more leakage flows, voltage drops due to resistance and self inductance.
A 25 kV distribution network consisting of three 30-km distribution feeders connected in parallel supplies power to a 36 MW/10 Mvar load (0.964 PF lagging) from a 120 kV, 1000 MVA system and a 120kV/25 kV OLTC regulating transformer. Reactive power compensation is provided at load bus by a 15 Mvar capacitor bank.
The heightening use of electrical machinery, automation systems, computers, security systems and other sensitive electronic equipment will bolster sales of products such as voltage regulating transformers, advanced switchgear systems and power circuit breakers capable of controlling and monitoring incoming electric power.
