Hoʻohana ʻia ʻo SPAJ 140 C no ka pale pōkole koho a me ka pale honua-hewa o nā mea hānai radial.

Hoʻohana ʻia ka relay over-current a me ka honua-fault relay SPAJ 140 C no ka pale pōkole koho a me ka pale honua-hewa o nā mea hānai radial i nā ʻōnaehana paʻa paʻa, kūpaʻa a impedance-earthed.

ʻO kēia relay palekana i hoʻohui ʻia me kahi ʻāpana over-current a me kahi ʻāpana hewa honua me nā mea hiki ke hele a me ka hōʻailona.

Hiki ke hoʻohana ʻia kēia mau relays no nā noi ʻē aʻe, e koi ana i ka pale hoʻokahi, ʻelua, a i ʻole ʻekolu-phase over-current. ʻO kēia hui ʻana o ka over-current a me ka honua-fault relay e komo pū kekahi me kahi ʻāpana pale pale kaapuni-breaker.

Ka laulā: Hoʻohui i ka overcurrent a me ka pale honua-hewa

Nā pōmaikaʻi huahana: ʻO ka relay pale helu helu maʻamau i hoʻohana ʻia ma ka mākeke.

Nā hiʻohiʻona huahana:

1.Easy-to-hoʻohana relay me nā hana koʻikoʻi no ka pale ʻana i ka hewa o ka wā a me ka honua.

ʻenehana 2.Proven: ʻEkolu-ʻaoʻao, haʻahaʻa-hoʻonohonoho ʻana i ka ʻāpana overcurrent me ka manawa paʻa a i ʻole ka inverse definite definite minimum time (IDMT) hiʻohiʻona.

3. ʻEkolu-ʻaoʻao, kiʻekiʻe-hoʻonoho pae overcurrent wae me ka manawa koke a i ʻole ka hana manawa ʻike ʻia ʻo Low-set earth-fault unit with definite time or inverse definite definite minimum time (IDMT) hiʻohiʻona High-set earth-fault unit with instantaneous or definite time operation.

4.Built-in circuit-breaker failure protection: Ke nānā mau nei ka ʻōnaehana nānā ponoʻī i ka hana o ka uila a me ka microprocessor.
