The Ultimate Inrush Current Limiting Solution

The VIZIMAX SynchroTeq is an advanced circuit breaker controler for ultimate limitation of inrush currents produced by power transformers' energization.

SynchroTeq is suitable for single-pole operated (Independent Pole Operated) and three-pole operated (Gang Operated) circuit breakers in new or existing installations. SynchroTeq is a modular solution for all circuit breakers (HV & MV), regardless of their manufacturer.

The SynchroTeq MVX is the most compact unit designed for MV switchgears applied to power transformer energization.

The Oil & Gas industry is a heavy consumer of reactive power because of its use of a large number of pumps, recompressors and other heavy equipment. Control reactive power allows voltage fluctuations limitation, power factor management and electricity bills limitation. Companies require FACTS to regulate reactive power balance; it corrects voltage fluctuations, reduces electricity bills and meets Utility Grid Code requirements.

Equipment operated within FACTS relies on medium and high voltage circuit breakers to energize or de-energize capacitor banks, shunt reactors, filters, SVC, STATCOM, etc. However, an uncontrolled or random load switching operation causes voltage disturbances and inrush currents. These may damage circuit breakers and equipment within a substation, alter power quality and lead to equipment failure or to blackouts.

The SynchroTeq controlled switching device improves reliability and stability of FACTS solutions: while switching loads, it operates circuit breakers at the optimal moment to prevent transients such as inrush currents and voltage disturbances. Thanks to its fast switching technology, the SynchroTeq helps FACTS quickly adjust the power factor.

Benefits:

• Increases revenue as downtimes are minimized
• Complies with Utility Grid Code requirements and avoid associated penalties
• Leverages power factor correction techniques
• Limits maintenance frequency for voltage dips and transient elimination
• Ensures power stability and reliability
• Quickly adjusts the power factor through fast switching of capacitive loads
• Improves voltage control of offshore platform

As a large electricity consumer and producer, the Oil & Gas industry has to meet electric Utility Grid Code requirements when connecting onshore or offshore extraction sites, refineries and oil or gas power plants to the distribution or transmission network.
The grid code relies on the reduction of a rapid voltage change. It specifies that usually a voltage change has to be no greater than 3% and 5% for transmission and distribution networks, respectively. In this regard, power transformers become a mission critical asset.

One of the main causes of voltage disturbances is the energization of a power transformer. In fact, uncontrolled power transformer energization generates voltage disturbances and inrush currents that can reach up to 12 times the rated current. The inrush current may cause nuisance tripping of the station protection or may induce voltage dips that go over the utility’s limits. Both cases require mitigation strategies.

This is when the SynchroTeq controlled switching device becomes necessity, since it is capable of mitigating or completely eliminating inrush currents caused by transformer core flux saturation.

Benefits:

• Increases revenues with facility uptime optimization
• Complies with Utility Grid Code requirements and avoid penalties
• Decreases risks of production site shutdown and product failure
• Prevents downtime caused by network instability and voltage dips
• Ensures stable and reliable electricity from the utility
• Improves energy efficiency
