As a result of rising cost of oils,

increasing environmental

regulations, liability and disposal

cost, and new stringent vacuum

requirements for manufactures

warranties to .4 Torr @ 48hours, it

is no longer economical to replace

electrical insulating oils with new

fluid. Instead, proper treatment of

these fluids with our proven Hi-Vac

Series renews dielectric strength

and lowers residual water content

by restoring oils to their original

strength through vacuum

dehydration & purification.

Improvement of the entire insulating

media of power transformers is

obtainable with our HHV series High

Vacuum (Hi-Vac) Oil Purifier. Our design meets the operational,

economic, and environmental needs of industry and maintains the quality

of insulating oils at the time of initial impregnation, filling at the factory,

and maintains the same quality in field operation.

Our proven Hi-Vac provides reportable dehydration, degasification, and

filtration techniques that remove even trace amounts of water to less than

5PPM and gases to less than 0.25%. An easy to read flow chart is

provided on the electric panel and is superimposed over all switches,

buttons, and indicating/warning lights. Our Hi-Vac can be used as

stationary units or manufactured within a variety of trailer configurations

to be completely portable or self contained.

their dielectric strength

Cold Trap Oil Wetness Determination Under Transformer Blank Off Conditions

888-910-7543

www.HENEKMFG.com

During certain phases of transformer restoration it is of critical importance that

as much moisture as possible be removed from its internal sections. This

phase is called the “dry out” phase. The task is accomplished by attaching the

transformer to a vacuum pump/blower system at the auxiliary connection.

Functionality

When all leaks on the transformer are sealed to the lowest possible point,

vacuum can be pulled on the transformer internals. This is normally the area

of ½ to 1 torr (1/2 – 1 micron), the only flow that may enter the vacuum pump

must come from the transformer and pass through the cold trap. Any water in

the transformer will turn to a vapor (steam) under these low vacuum conditions

and freeze as it passes in the cold trap (temperature -80°F to -40°F). It should

also be noted that any other liquid contaminants in the transformer that can

boil at temperatures equal to or below water may also vaporize and pass

through the vacuum system and finally return to a liquid state and move into

the atmosphere or the vacuum pump oil.

When charged with liquid nitrogen and nitrogen gas, the cold trap is self

contained. It is electrically and pneumatically controlled by a single

temperature sensing device on the chiller side and is automated to reduce

liquid nitrogen consumption during the chilling

operation.

To thaw the collected water for measurement, the

cold trap is equipped with a hot water/glycol

solution tank that is heated by a manually activated

emersion heater. When activated, the heater

increases the temperature of the glycol solution to

a preset point before it cuts out and recycles. The

glycol tank is equipped with a circulating pump that

can be turned on manually to distribute the hot

glycol throughout the heating coils (approximately

170°F). The ice is thawed and contained in the cold trap until it can be

measured.
