in power exports

WINNIPEG (CP) — In- _ creased exports of electrical power from Manitcba to the United States could make the province a leader In designing improved high- .

systems.

The physical plant of Manitoba Hydro, ‘with its hundreds -of kilometres of

. high-voltage ‘ines, provides

the. “practical, large scale

such research, says Rdmund

Kuffel, dean ‘of engineering

at, the ‘University of Mani-' .

Kuffel adds that the ex- pertise of Manitoba Hydro staff also gives-the province 4 head'slart in the field,

A practising dlectrica) engineer, Kutfel is trying to establish a centre for high- voltage, direct-current studies at the university,

Projects at the centre. would include finding better transmission systems and

insulation materials ana studying the possibility of underground long-distance lines. . ;

Abel Katahcire, one of Kuffel’s student assistants, describes another, more

Manitoba now has two 230- kilovalt lines running from its series of northern power stations to North Dakota and northern Minnesota,

With its current generating capaelty, Manitoba Hydro waa able to sell $25-million -worth of surplus electricity in the first four months of 1979, about 60 per cent of it to the U.S. Tishinski says the U.S. purchases .are 15-to 20-per-

cent higher than for the same period last year.

Kuffel, a member of the Manitoba Hydro board of directors, says the federal government would pay half the costs for setting up the centre with the other half coming from the utility's operating budget.
