RetrofittingExistingControls&Breakers

IntroductionWhen considering whether to maintain & upgrade existing equipment opposed to replacing older aging

existing equipment, facilities must take into account the capital cost, along with potential disruption to the

mission critical processes and workflow during the course of replacing equipment that can be a massive

undertaking to extend the life of a system. Russelectric has a Retrofit solution than can provide a fraction of

the downtime to complete than replacement, is a less expensive alternative, maintains the ability to improve

reliability as new equipment would, upgrades technology to current standards and increases serviceability of

equipment.

Retrofitting the Utility Control and/or Generator paralleling control switchgear: There are many specific items/devices that are no longer available and do not have direct replacement parts. Older devices and technology may not have modifications available to be completed on an itemized basis and the majority have become unserviceable and the reliability can be concerning to mission critical facilities. This leads to the recommendation that the control sections and breakers be upgrade in their entirety rather than replace the entire switchgear where the framework, bus work are mechanically still in good condition. This process will modernize and upgrade the existing controls to the latest technologies and allow for increased reliability and serviceability. In the end, the existing buildings power system is not modified, the equipment remains intact as is and the interior and door controls of the existing equipment is brought up to the latest control standards and would restore reliability, serviceability for the controls and provides all the benefits to new switchgear.

OverviewofRetrofitProcessTo summarize the retrofit of the controls; new controls are designed, Built and Tested at Russelectric. The retrofit control panels utilizing our current standard devices, including PLC’s & Operator interface panels. All devices would be prewired on electrical plates, mounted and wired on temporary open frame cubicles for testing and shipping (The panels are removed at the site and installed in place of the existing), with everything tested in the factory just like a new switchboard. We then ship the out the open frame cubicles individually to the site along with our temporary control panel setup which we would use to keep the site with automatic backup power and operational while we remove the existing controls and install the new. The site would experience a few transfers in the beginning and multiple transfers during final testing but for the duration of the work, the facility will have automatic operation & emergency backup with our temp controls. This process has been completed at many mission critical facilities in the US and the process has been refined to suit the requirements of each site as required.

TempPanelControlsforRetrofittingExistingSystemsUseThe temporary controls panel built by Russelectric as shown in the picture below, allows for the opportunity

to control existing switchgear in a temporary fashion while controls are being replaced. This temp panel acts

as a master control cubicle and transfer control cubicle(s) and uses the existing generator control cubicles to

control the paralleling operations in an automatic mode of operation.

The temporary controls are setup to accommodate Paralleling control systems with 5 or less generators with

or without a gen bus tie, (can be expanded up to 8 generators), (8) load controls priorities for ATS or Breakers,

(2) Transfer pairs with a load bus tie (H system).

TypicalRetrofitOverviewTo summarize the retrofit of the

controls; new controls are

designed, manufactured and fully

tested at Russelectric just as a new

system would be produced. The

retrofit control panels utilize

Russelectric latest standard

devices, including PLC’s & operator

interface touch panels. All devices

would prewired on electrical panels

designed to be mounted in the

sites existing switchgear. These

panels would be mounted and

wired on temporary open frame

cubicles for testing and shipping

(the panels are removed at the site

and installed into the existing

cubicles). With everything tested in the factory just like a new switchboard, Russelectric then ships the

cubicles to the site along with the temporary control panel setup which is used to keep the site with automatic

backup power and operational while the removal of the existing controls and the new controls are installed.

The site would experience a few transfers at the commencement and multiple transfer during final testing

after the retrofit is complete. For the duration of the work, the system will have automatic operation &

emergency backup power with Russelectric temp controls.

FunctionsThe temporary panel consists of three separate panels EXPS, TPF (front) and TPR (rear). All of the temporary

panels have premade harnesses for the inter‐panel connections. The panels also has premade harness’s that

connect to the switchboard it will be controlling. There are Wago XCOM connectors on the temp panel side

and lugs on the switchboard side for connection. The temporary panel has the functions listed below.

1. Best Battery Circuit: In the EXPS panel there is a Sola‐HD Power supply with an interconnect terminal

strip to a remote 120VAC source. The front of the EXPS panel has IDEC annunciation that indicates the

120VAC input and 24VDC output of the Sola‐HD Power Supply is energized. In the TPR panel there are

separate 15A ABB breakers and Crydom diodes for each engine battery input. The outputs of the

diodes connect to the Sola Power supply to make up the 24vdc best battery circuit.

2. Manual Breaker Closure: On the front of the TPR panel is a synchroscope, sync selector switch and

breaker control switch that allows an operator to close up to 4 generator breakers. A Crompton sync

check relay and Wago MCK kit are installed in the temporary panel to provide for safe closure of the

generator breakers.

3. Automatic Dead Bus Closure: There are PLC outputs in the TPR panel that energize relays for the dead

bus closure of up to 4 generator breakers. Premade wiring harnesses are connected to dry contacts of

the dead bus relays.

4. Automatic Sync Enable Outputs: There are PLC outputs in the TPR panel that energize relays to enable

the existing automatic synchronizers in the switchboard being modified.

5. Engine Start Outputs: There are PLC outputs in the TPR panel that energize relays to automatically

start up to 4 engines during a power failure or load test

6. Engine Status Inputs: The engine status inputs listed below are in the TPR panel for four engines.

a. Engine at rate voltage/frequency (G‐Relay)

b. Generator Breaker Closed Input

c. Engine Locked Out Input

d. Spare Generator Alarm/Status Input

7. ATS Engine Start Inputs: There are PLC engine start inputs in the TPR panel for up to 8 ATS’s

8. ATS/ Distribution Breaker Load Control: PLC outputs in the TPR energize relays for 8 load control

priorities. Premade harnesses are connected to dry contacts on the load control relays.

9. Load Control Annunciation: Small Dialco Lights are mounted on the front of the TPR panel to indicate

the status of the load control outputs. The Block Transfer lights are red. The load shed lights are green.


R E V 1 . 0 – 0 2 / 0 8 / 1 7 3 | P a g e

10. Generator Breaker Annunciation: A 2 by 4 IDEC light box is mounted on the front of the TPR panel to

display the closed status of the generator breakers and if the engine is at rated voltage and frequency

11. Utility “H” System Control: There are PLC inputs and outputs in the TPR panel to monitor and control

two utility main breaker, two generator main breakers and two load bus tie breakerds. Control of these

breakers would be in open transition mode of operation. The inputs listed below are being monitored

for the Utility “H” system control.
