Verb tenses indicate the time at which an event occurred. It is actually the property of the verb form and in English there are 3 basic tenses: past, present, and future.
Each of these tense has a perfect form that provide the following indications: progressive form which is used for indicating an ongoing action, perfect form which is used for indicating a completed action, and a perfect progressive form which is used for indicating an ongoing action that will be completed at some definite time.

1. Past simple expresses an event that occurred in the past. Most past simple verbs end with "ed". However, there are others that have irregular forms.
I went.
2. Past Perfect expresses an event that took place in the past before another past action. This tense is formed by using "had" with the past participle of the verb.
I had gone.
3. Past Progressive expresses a past event which was happening when another action took place. This tense is formed by using the verb 'be' as was/were with the verb form ending in -ing.
I was going.
4. Past Perfect Progressive expresses a past, ongoing action that was completed before some other past action. This tense is formed by using 'had been' and the present participle of the verb (the verb form ending in -ing).
