Mobile Substations

Applications of Inesing Mobile Substations:


Lightning Arrester Protection level in coordination with transformer insulating level. In case windings have two or more voltage levels, multiple lightning arresters are used (one for each voltage level), which are interchanged at the same time the winding voltage level is changed.

Disconnecting Switch Single or three pole with capacity to interrupt transformer magnetizing currents. Can be operated locally or from a remote location.

HV Breaker Dead tank SF6 circuit breakers are commonly used, with motor-wound spring operating mechanism, operable on even loss of auxiliary power.

S&C Circuit Switcher Circuit switchers feature SF6 gas filled interrupters and single-pressure puffer technology for restrike-free, non-current chopping performance. Used when limited capacity due to space or alarm conditions are presented.

Power Fuses Normally mounted between the lightning arrester and the transformer. Selected in accordance with voltage and current ratings.

Potential transformer and current transformer Used to reduce voltage to 120 V and current to 5A for metering and protective relays. They also provide insulation between the primary and secondary circuits. For 25 kV and above PT's and CT's are suitable for outdoor use and below this range for indoors or outdoors in accordance with customer specifications.

Bushings Bushings can be supplied as standard ceramic or with silicon insulation. Bushings are selected in accordance to voltage and current requirements.

Transformer Core or Shell type, with same thermal, mechanical, dielectric and economic advantages of Tamini power transformers. - Compact design to optimize the transformer volume and reduce its total weight. - Designed to handle average winding temperature rise of 65, 75 or 95 C. - NOMEX/ pressboard or NOMEX insulation

Forced oil and air cooling (FOA) Forced oil cooling consists of a seamless tubular cooler heat exchanger plus a submerged pump and motor .A bearing wear monitor is proposed which stops the pump in the event bearing wear has reached and unsafe level.

Tap Changers The transformer could have one or more de-energized tap changers (DTC) on high or low voltage winding, delta-wye switches or on load tap changer (LTC) on high or low voltage winding. On all cases, external operating mechanism allows the voltage connections to be changed without opening the tank. LTC may be Resistive or inductive type and DTC may be Series-Parallel type.

High temperature liquid Several high temperature oil types may be used for the transformer: Midel®, FR3®, Silicone oil or Beta fluid.

Monitoring Equipment Online monitoring is an important tool for early fault detection and real time condition assessment. IEM may provide online DGA and moisture monitoring, online PD monitoring and temperature and load monitoring.

AUXILIARY TRANSFORMER FOR CONTROL POWER

Oil Immersed, single or three phase and permanently connected to the low voltage of the main transformer.

Low Voltage Breaker

A vacuum or SF6 breaker normaly provides low voltage protection agains short circuit current. The breaker and its controls are mounted on the trailer's low voltage end or in a different trailer depending on customer specifications. Three phase, metal eclosed, metal clad single busbar switchgear has a hermetically sealed primary enclosure, which provides protection against accidental contact ans is independent of environmental effects.

Protectiv Relays

For protection against abnormal transformer differentials and sudden gas pressure. A wide variety of relays can be installed to meet specification needs.
