BTPC

bypass isolation transfer switch open or closed transition 150 – 4000 amps

BTPC bypass isolation transfer switches combine a drawout automatic transfer switch with isolation mechanism and a manual bypass switch, to provide redundant power transfer and re-transfer capability for critical-need applications requiring a reliable power supply to the load. BTPC switches are available with closed transition for transferring critical loads without interruption.

Like conventional transfer switches, BTPC transfer switches are designed for operation and switching of electrical loads between primary power and standby generator sets. The switch monitors both power sources, signals generator set startup, automatically transfers power and returns the load to the primary power source when the utility returns and stabilizes.

Features

PowerCommand® control: A fully featured microprocessor-based control with digital display. Controls allow operator to enter settings and make adjustments to software-enabled features easily and accurately.

Accommodates up to 8 event schedules.

Closed transition available: By briefly connecting the two sources (for 100 msec or less), the transfer from the alternate source back to the normal source occurs without interruption in the power supply to loads.

Programmed transition: Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period, as recommended by NEMA

MG-1 for transfer of inductive loads.

Closed door drawout operation:

Bypass and total isolation of the automatic transfer switch occurs behind closed doors, to provide arc flash protection for operator.

For critical loads: Suitable for use in emergency, legally required and optional standby applications.

Transfer switch mechanism Bypass mechanism

Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources.

Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature).

True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator.

High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover.

A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components.

Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design.

Manual bypass switch mechanism allows the operator to select either the normal or emergency source by closing the bypass contacts. Visual indicators show bypass “source selected”, bypass

"closed" or "open" to either source, and automatic transfer switch isolation or

"disable." Bypass of the automatic switch is accomplished with permanently mounted, mechanically operated devices without disturbing the power supply to system loads, and without opening enclosure door.

Isolation contacts allow the automatic transfer switch and the bypass switch to be separated electrically and mechanically. The automatic transfer switch is isolated by a drawout mechanism similar to that used on power circuit breakers on transfer switches rated 1200 amps and less. On

1600-4000 amp models the drawout carriage is wheel-mounted.

Protective safety shutters, provided on switches up to and including 1200 amps, cover the stationary power terminals on the bypass switch when the automatic transfer switch is isolated and removed.

The drawout mechanism can be latched in one of three positions: “connected”, “test”, and “isolated”. In the connected position the mechanism is locked. In the test position, the automatic switch is isolated but the controls receive power.

In the isolated position, the automatic switch is completely isolated.

The bypass switch mechanism is identical to the automatic switch except it is mechanically operated rather than electrically operated. Mechanical interlocks prevent operation of the bypass or automatic switches in any mode that would result in the interconnection of the sources.

Time-delay functions

Engine start: Prevents nuisance genset starts due to momentary power variation or loss. Not included in utility-to-utility systems.

Transfer normal to emergency: Allows genset to stabilize before application of load. Prevents power interruption if normal source variation or loss is momentary. Allows staggered transfer of loads in multiple transfer switch systems. For genset-to-genset applications, delays transfer of load from lead to secondary generator.

Re-transfer emergency to normal: Allows the utility to stabilize before re-transfer of load.

Prevents needless power interruption if return of normal source is momentary. Allows staggered transfer of loads in multiple transfer switch systems. For genset-to-genset applications, delays re-transfer of load from secondary back to lead generator.

Engine stop: Maintains availability of the genset for immediate reconnection if the normal source fails shortly after transfer. Allows gradual genset cool-down by running unloaded. Not included in utility-to-utility applications.

Elevator pre-transfer signal: Requires optional relay signal module (M023). Delays transfer for pre-set interval of 0-60 seconds to prevent a power interruption during elevator operation.

User interfaces

Basic interface panel: LED indicators provide at-a-glance source and transfer switch status for quick summary of system conditions. Test and override buttons allow delays to be bypassed for rapid system checkout.

Digital display: The digital display provides a convenient method for monitoring load power conditions, adjusting transfer switch parameters, monitoring PowerCommand network status or reviewing transfer switch events. Password protection limits access to adjustments to authorized personnel. The digital display (M018) is standard on the BTPC.

User interface options

Bar graph meter display (D009): An LED bar graph display provides an easy-to-read indicator of the level of power being supplied to the load.

Information displayed includes: 3-phase voltage and current, power factor, and kilowatts. Green, amber and red LEDs provide at-a-glance indication of system acceptability.

Front panel security key (M017): Locks front panel to prevent access to digital control settings. Prevents unauthorized activation of transfer or test functions.

Control options

Relay signal module (M023): Provides relay output contacts for sending information to the building monitoring and control system. Relay outputs include: Source 1 connected/available, Source 2 connected/available, not in auto, test/exercise active, failed to disconnect, failed to synchronize, failed to transfer/re-transfer, and elevator control pre-transfer signal.

Loadshed (M007): Removes the load from the emergency power source by driving the transfer switch to the neutral position when signaled remotely. Transfers load back to the emergency source when the signal contacts open.

Immediately re-transfers back to the primary source when available. For utility-to-generator applications only.

PowerCommand network interface (M031):

Provides connection to the PowerCommand network. LonWorks compatible for integration with building monitoring and control system.

Load power and load current monitoring

(M022): Measures load phase and neutral, current, power factor, real power (kW) and apparent power (kVA). Warns of excessive neutral current resulting from unbalanced or nonlinear loads. Minimum current level detection is 3%.

Transition modes

Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by

NEMA MG1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-10 seconds, default 0 seconds. Programmed transition is standard on 150-1000 amp switches, and optional on 1200-4000 amps.

Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up on

150 – 1000 amp switches and 1200 – 4000 amp switches that support programmed or closed transition. If sources are not in phase within 120 seconds, the system will transfer using programmed transition.

Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply.

Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load.

The control can be programmed to alternate between the two gensets at a set interval up to

336 hours (2 weeks).
