The 1 Phase Secondary Injection Kit from Prism Test & Measure Pvt. Ltd. is a reliable and high-precision testing instrument designed for testing, commissioning, and maintenance of protection relays, current transformers (CTs), potential transformers (PTs), and other protection devices used in electrical power systems.

This system provides accurate single-phase current and voltage injection to simulate real operating conditions in electrical protection circuits. It allows engineers and technicians to evaluate relay performance, verify protection schemes, and check system functionality efficiently.

The kit is equipped with digital meters for voltage and current measurement, adjustable AC/DC voltage output, multiple current ranges, and programmable timer functions. With robust construction and built-in safety protections, the 1 Phase Secondary Injection Kit is widely used in power plants, electrical substations, switchgear testing, transformer testing, and electrical maintenance laboratories.
