Import 33kv Current Transformer — Buy in wholesale FOB from Supplier in India

The 33 kV current transformer from Power System Control is a wound-primary and window-type instrument transformer designed for medium-voltage power distribution and electrical monitoring systems in India. It measures alternating current accurately, stepping high primary currents down to standardised secondary values (typically 1 A or 5 A) for metering and protection relays. The unit is built to withstand 33 kV nominal system voltage with robust insulation systems suited to tropical and subtropical climates. Exact ratio, accuracy class, and thermal current ratings should be confirmed with the supplier before final specification.

Construction employs high-grade electrical steel cores to minimise hysteresis and eddy-current losses, with copper or aluminium windings depending on the design variant. Insulation is typically resin-cast or oil-impregnated paper, providing Class F or Class H thermal performance (standard for 33 kV indoor and outdoor designs). The window-type variant accommodates busbar or cable primary conductors without dedicated primary windings, while the wound-primary version suits lower primary currents. Typical accuracy classes for metering are 0.2, 0.5, or 1.0; protection classes are 5P or 10P, with accuracy limit factors of 10, 15, or 20 (standard per IEC 60044-1 / IS 2705).

Primary buyers include state electricity boards, private transmission utilities, industrial substations, and switchgear OEMs across South Asia, Africa, and the Middle East. Applications span revenue metering, overcurrent protection, differential protection, and power-quality monitoring in 33 kV switchgear, ring-main units, and outdoor pole-mounted installations. Trade terms, MOQ, and lead time are not stated in the source data and must be negotiated directly with Power System Control in New Delhi.

Power System Control is based in New Delhi, India, and operates as an organic-tier supplier within the electrical equipment sector. The supplier profile carries a harbour trust tier, which indicates a baseline verification level on the marketplace platform. Notably, the response rate is recorded at 0.00 percent with an average response time of zero hours, meaning no response data is currently available. Buyers should therefore anticipate potential delays in initial contact and plan procurement timelines accordingly.

The listing presents itself as a manufacturer or authorised representative of 33 kV current transformers, offering both wound-primary and window-type constructions. No verified factory audit details, ISO certificate numbers, or specific production capacities are disclosed in the source material. The company does not state its year of establishment, employee count, or annual revenue. Prospective buyers are advised to request direct evidence of manufacturing capability, quality management system certification, and reference installations before committing to volume orders.
