PCIT Primary Current Injection Test Set
Primary Current Injection testing is done with the aim to identify how a heavy electrical system operates under various levels of current loads. By injecting the current into the electrical system, it is easy to measure if the breaker will trip or fail and also how long the current stays live before the circuit breaks.
Available in various output current and ranges.
Note: Ranges for which prices are not mentioned can be enquired for. Shipping is chargeable extra as per location and order.

Description
High current or high voltage situations at large electrical installations like power substations use primary injection testing, wherein a large current, between 100A to 20000A, depending on the system and the requirements, is injected directly on the primary side of an electrical system (like a circuit breaker). The testing is done with the aim to identify how an electrical system operates under various levels of current loads.
Any failure during activation of Circuit Breakers can cause disastrous damage to the electrical system, if they have gone through a long period without activation, as can be the case sometimes. Using a Primary Current Injection on a breaker that has been non-active is probably the best way to reconstruct the condition of a current spike. By injecting the current into the electrical system, it is easy to measure if the breaker will trip or fail and also how long the current stays live before the circuit breaks.

- When testing, especially if the protective gear is connected to the power line via a current transformer, it is advisable to carry out primary injection testing.
- These sets have been designed to enable the users of heavy electrical equipment to carry out such tests as have been described above with a maximum efficiency at minimum cost, providing a convenient of delivering, controlling and measuring a heavy current in a comparatively low voltage low impedance circuit.
- Ideal for testing circuit breakers, ammeters with or without current transformers and much other applications where a heavy current supply of short duration is required.
- Current output: Can Vary from 100A to 4000A
- Capacity: Can vary from 1kVA to 40kVA
- Number of Ranges : Can vary from 1 to 3
- Duty Cycle : 5 mins ON and 5 Mins OFF of continuous duty cycle
