Uganda Power Company Renews Order, Ships Primary Current Injection Kit

A primary current injection kit is specialized testing equipment used to inject a high current into electrical circuits for assessing the performance and protection settings of power system components. This kit helps power companies like Uganda Power Company maintain grid reliability by verifying circuit breakers, transformers, and protective relays accurately.

What is a primary current injection kit?

A primary current injection kit is a robust device designed to deliver controlled high currents into electrical systems for testing and calibrating circuit breakers, relays, and transformers. It assesses the system’s response to overloads, faults, and protection trips, ensuring safety and operational integrity. This kit is widely used by electrical utilities and manufacturers globally, including China-based factories producing them for OEM and wholesale markets.

How does a primary current injection kit work?

The kit injects a programmed high current, either in series or parallel, into the primary circuit under test. It measures the response time and behavior of protective devices like circuit breakers and relays under realistic load conditions. Equipped with digital meters and control systems, modern kits from manufacturers such as Wrindu offer precise current adjustment, real-time data display, and recording to verify system protection accurately.

Which features are critical in a primary current injection kit?

Essential features sought by manufacturers and suppliers include:

• Adjustable high current output (up to thousands of amperes)

• Accurate current measurement (±0.5% or better)

• Stable sine wave current output with low distortion

• Digital display for current, time, and relay trip characteristics

• Portable design for field and factory testing

• Safety features such as thermal and overload protection

• Compliance with IEC and ISO quality standards

Wrindu’s primary current injection kits integrate these capabilities, catering especially to China’s OEM, factory, and wholesale clients.

Why do power companies like Uganda Power Company renew orders for these kits?
